I'm sorry they are not in alphabetical order, but hey, can't have everything (: . As stated before, I did NOT create these and I do NOT claim credit. Just trying to help speed things up! Proper credit to whoever created them is due. I do realize the entire car diagram is unreadable - I have it as a 3.75 meg file, which I'll upload somewhere and link to it later.

[DMCH James]

Sean? Weren't these your work? May I post them at DMCHelp in the Resources forum thread there, "just in case" something happens to the forum in the future?

Glad to see the site back, hope the old data comes along at some point!

Does anyone have a backup of that color diagram showing all the relays and fuses? I never got around to printing it out and putting it underneath the access panel like a few other folks have done. :(

EDIT:
Fuse 4: Directional Indicators (only)

Some early modles have an empty space where the Fan Fail Module (Blue) is shown with it and the others in the row shifted to the right (This can cause confusion since it is well known that the Fan Fail was abandoned...)

Here is a copy of the fuse and relay area schematic with a little extra text written up on it (I also am not the original author so I hope it is okay to post these here):

As the author I'm wicked happy you kept a copy and posted it! I've been scouring my computers trying to find it. I have all the original PNGs for all the schematics I did BUT that one and it was driving me nuts that I couldn't post it.

THANK YOU!

Does anyone have a wiring schematic for the radio and speaker connections? I bought a new deck today so the Craig is coming out. It might be on the full colour schematic somewhere but I can't seem to find what part of the drawing it's on.

There's a basic one on page M:18:17 of the shop manual ;)

Installing a new radio isn't that hard to do. You may find it more annoying to cut the HVAC/radio plate to accommodate the new unit (unless you bought a DIN plate).

There are two fused wires that power the unit; a light green with white stripe wire (only live when ignition is on) and a purple wire (always live). Your installation instructions will tell you where these need to be wired to your new harness. I left the fuses in place, even though the new deck will be fused in and of itself. A bit of extra insurance, I suppose.

The speaker wires are thin little things, unless they've been replaced in the past. Because you really should remove the center console to do your radio install, you will be able to trace each speaker's wire to identify them. If they are still original (wires and speakers) you may want to consider replacing them......no new deck sounds good with 17W speakers!

I can't remember; does your car have the fender mount antenna? If so, you'll have a wire or two in the new harness that you won't use. If you have or are moving to a rear power antenna, there's a "sense" wire that tells the antenna to raise or lower based on if the tuner is in use or not.

The new harness comes with its own ground. You'll see where the ground spot is with the console beneath (it's on the passenger side). The speaker wires will now hook directly to their respective places on the wiring harness as the instructions will describe.

Of course, disconnect your battery before you begin. Oh, and if you have an original headlight switch, have you considered adding a relay to the wiring to save it from meltdown? :D

Somewhere, Welmoed posted a pinout of the original radio harness connector. That might also come in handy.

Perhaps a bit late, but here's the connector pinout (previously sent to be added to the schematics section).

I also include here the pinout of the side mirror switch (also previously entered).

Assume they were lost in the transition of the forum.
Anyway here they are again (moderator: can you add them to the schematics section?)

Here is one I have.

I know it's possible that way.
However I only need one out of the many in that message.
And precisely that is not possible (contrary to just picking a single attachment, which is possible).
The one I'm looking for is the diagram of the GC electronics.

BTW: In that message I also do not find the bulkhead connector placement 'picture'.
Should you have this bulkhead file, I love to get it (I believe it's called bulhead connectors and is a JPEG file).

Thanks,
Welmoed.

[Ron]

??? I can save them off individually (as above, try right clicking in the center of the pic).
I have notice that occasionally I have to click a pic to make it larger, then click it again in the new window and it will open yet another window that you can save it from in higher rez.

Anyway, I put all of the GC stuff in its own thread HERE (http://dmctalk.org/showthread.php?350-Automatic-Transmission-Governor)
I can email them if it just don't work for you (PM me)

Does a simplified schematic exist for the brake warning light circuit (like the ones at the beginning of this thread)?

It's not a complicated circuit and I didn't see one, but thought I would at least ask.

In the main wiring diagram for everything, you can see the brake warning light wiring:

29055

What got me wondering is from trying to troubleshoot an intermittent brake warning light. It comes on with the parking brake handle most of the time, but also will just decide to not work for a while and then suddenly start working again. It stopped working this week one day and so it won't remind me the parking brake lever is pulled up. I was leaving a cruise night the other day and drove much of the way home before realizing someone pulled it up on me at the show. Dumb of me not to realize right away, but I guess I rely on the bulb coming on and not the handle brushing against my leg.

The part that I was questioning was when I got into the brake fluid reservoir area and looked at the switch on top of the reservoir. It has never functioned on my car as another way to turn the light on. I know it should, but it doesn't. The connector has three terminals yet my harness end of the connector has the middle wire clipped and only has about a millimeter of it poking out still. The diagram seems to indicate only two wires, but I wasn't sure so thought I would ask.

I see there is a diode down a little further on the harness and I'll check it's connections as well. It seems like even if the diode were having problems, it shouldn't affect the parking brake lever wiring as it appears to come after it. Not sure about that though. I don't imagine it is the bulb itself or some fuse as it comes on at times just not consistently.

As a test, I could just jumper the two outside connections on the harness connector and it should basically simulate the switch completing and turn the warning light on, right? (on the reservoir switch that is... although the same test you would think should work on the parking brake lever switch too).

[Bitsyncmaster]

I don't see a diode on my schematic. It looks like either switch closed would turn on the light, so it must just be your hand brake switch or it's connections that are bad.

By the way, I always set my parking brake fully (I don't keep it in gear). So if I forgot the brake my car would stall since my parking brakes hold very good.

Interesting you mention about stalling. That's exactly what made me notice it eventually. I'm squaring away a bit of an idling issue and then I think I confused the two together because as I was leaving the cruise night and going home, I got behind a steady stream of cars from the 30s or 40s doing about that speed in km/hr and so I couldn't give it much gas while in DRIVE or I'd ram into them. Goofy how I think it had more to do with the parking brake than the idle, but you can trick yourself sometimes by being to focused on one aspect and not the other.

I'll have to double check on the diode. There definitely appears to be one just beyond the two wires the branch off to the reservoir switch and it looks to be wrapped up with another section of wiring harness. I thought that was what the black rectangle on the main diagram was showing?

I wonder what that black rectangle represents also. I never really gave it much thought. I would have guessed it to indicate a connector but I don't know if that's always true.

[robvanderveer]

Those black rectangles are all over the schematic, for example near the wing mirror motors:29061

[DMCVegas]

Some quick research shows that apparently there are international Schematic Symbols, and then US Schematic symbols as well. I had no idea, and feel pretty ignorant now. So apparently an empty box is the international symbol for a Resistor, and a filled box as we see here is an Inductor.

Perhaps these are integrated into the wiring harnesses to block RF noise from electrical motors and other sources from feeding backwards through the electrical system?

[Josh]

the only inline devices in the car are caps and diodes. No inductors.

I believe those are connections. Like for example where wires pass thru the bulkhead into the engine bay.

[DMCVegas]

I think it's a yes and no situation here. Yes, I now believe that my previous assumption was wrong, and that your's that these are connectors is correct. However, they're not bulkhead connectors. Those are separate and not listed. Let me explain.

It looks as though Lotus has had an evolution of sorts when it comes to drafting schematics from the Europa through the Esprit diagrams that I looked at. Absolutely fascinating stuff in terms of Lotus' thought process. The schematic is divided into 3 sections that physically represent the car. Left side of the page represents the front of the car, right side is the rear, center is the passenger cabin. The front and rear bulkheads are the dividing lines. Lotus would make a mark to show *where* the bulkheads would be in relation to the harnesses, and from there you would simply draw down an imaginary, vertical line. That line also represents the division of the harnesses into their 3 main sections. Example. (http://www.lotus-europa.com/manuals/misc/electrical/s2r-diag.gif)

This leaves us with 3 main sections represented by the harnesses of the same name accordingly: Front | Main | Rear

Within the division of the 3 sections the diagram does NOT show the Connectors on these 3 harnesses where they pass through the bulkheads and connect to one another. It is assumed that there is an understanding that they in fact are there.

Now, *within* those 3 sections, there can be separate sub-harnesses. Ie. an Engine Wiring Harness. Since these harnesses do NOT plug into/pass through the bulkheads, they have separate connectors that are represented by these rectangular boxes. Again, this great insight into Lotus' drafting process and why the Workshop Manual appears as it does: Lotus had their own thought process which they just assumed everyone was already aware of. So, if you have a separate sub-harness/circuit such as the ignition system or the audio system within a certain area, it is completely separate of the Local Harnesses, and its individual connectors are actually portrayed by these black rectangles. Example 2. (http://www.thelotusforums.com/forums/uploads/post-3419-0-64641100-1396975285.jpg)

So if you compare the Schematic to the mini wiring harness that is hardwired into the back of the window switch, it makes perfect sense!
http://dmctalk.org/attachment.php?attachmentid=29061&d=1405848079http://store.delorean.com/images/Product/medium/7062.jpg

Again, these are two separate sub-harnesses interconnecting so there is a representation of a connector on the schematic. However for items such as the Frequency Valve, Relay Sockets, Switches, & Diodes, those connectors/sockets only interface with the specific modules/components and not other harnesses, so there is no representation of a connector, as it is assumed the viewer already understands that they are removable.

The confusion is exacerbated with DeLorean because it has 4 main harness sections instead of 3. This is why it's so cluttered and damn confusing.

Lotus Esprit (any other car)
Front | Main | Rear

DeLorean DMC-12
Front | Main Roof | Rear

And to further this, Lotus never having to deal with a 3-Dimentional schematic for a car before chopped up the Roof Harness into several sub-harnesses within the Passenger Cabin.

If you can understand all of that, then you have a greater understanding of the wiring harnesses. If we ever had a community effort to finally clarify the harness, the best thing that we could do would be to highlight the 4 main harness sections with colored bubbles/fields, give the 4 harnesses their own individuals pages, and then refer back to the Workshop Manual's simplistic schematics for the sub-harnesses. In order to show the Bulkhead connectors on the 4 Harnesses, we would need to either completely rearrange the entire schematic, or we'd have to include a new symbol to differentiate these connectors from the others.

[robvanderveer]

I for one am very happy with the community work on the schematics so far, like the simplicated schematics, and the full color diagram. It makes life much easier compared to the original diagram, on which it is hard to trace a single line. So: thanks to all people involved.

[Farrar]

If you're replacing part of a circuit because one of the wires is damaged, you may find that you need a wire with insulation of a color or color combination that is not available in the U.S.

If you're like me, you may have a good idea in your head of what AWG you want, but that information isn't given on non-U.S. websites. When I was looking up wire from companies outside the U.S., I found myself wondering at the different ways wire size was given. Some had dimensions in cross-section and some in outer diameter, always in mm².

Using information I found on the Internet, I made this chart for my own easy reference, to convert between AWG, cross-section in mm², and diameter in mm². I am posting it here in case it may also come in handy for anyone else.

[robvanderveer]

On the topic of wiring thicknrss, please note that (at least in Europe) the so called Thin Wall wiring has become standard. As the isolation is a different material, it can be thinner and therefore the wire is more flexible and easier to work with. Please correct me if i'm wrong.. here's the source on the topic: http://www.autosparks.co.uk/index.php?content_page=52 and here: http://www.rdae.nl/draad-en-kabel/enkeladerig-draad/draad-info-pagina/ (dutch)

[Bitsyncmaster]

Insulation is available in two ratings for the most part. 600 volt or 300 volt. So it's not really the voltage rating for our cars but the thicker insulation can protect the wire more if there is abrasive action.

Some speaker wire I've seen 50 volt rated.

If you can get the circular mill value of the wire that will let you reference it to wire size (AWG). It also lets you know what two wires of one size would equal in another size.

example:
16 AWG has 2580 cmil, so two 16 AWG has 5160 cmil
13 AWG has 5180 cmil so two 16 AWG is better than 14 AWG but less than 12 AWG

Kind of along the lines of this thread.

Here's the wiring diagram for swapping over from the OEM power mirror switch to the new GM-style switch. It'll take you five minutes with this diagram.

[SpudMurphy]

I have a project Delorean, which has all the roof connectors uncoupled (under the T section).

I only had a quick look but was expecting the wiring colours in the male and female connectors to be the same - I think they are different?

If that is the case then, referring to the initial post, is there any similar diagram covering the roof connectors?

Thanks

[Shep]

Might be a bit late to you Spud, but did you check the other sticky here?

Anyone have a more detailed schematic for the mirror switch? I’ve bought a crossover part that has no pigtail, and need to create some kind of adapter. Would be helpful to know what wire’s what in terms of “left, right, up, down, mirror L, mirror R, ground” etc. If anyone knows.

Heyyyy now that’s what I’m talking about! Thanks so much, Ron!

Now if only I can figure out where to find a plug that fits the new switch I got, I could make up an adapter in no time. One step at a time.

[jawn101]

Oh, hmm. But what that doesn’t so much tell me is which wire “does” what. I can sorta infer a bit, but it’ll be a bit of trial and error to get the functional mapping right.
