Hi all,

I was looking over the wires in the engine!

I took a few pictures, I want to see whats the story with these wires. I'm clueless!!


1. Unplugged wire, it doesn't see to plug anywhere.

2. Another unplugged wire in the back.
http://i54.tinypic.com/dhbr4y.jpg

3. By the hatch light switch, A connector with 3 cut wires, then a Red & Brown wires coming out for the blue connector just rapped together not connected to anything.
http://i55.tinypic.com/x3s2dw.jpg


4. I was wondering about this wire, if it is supposed to be going through that direction??

http://i56.tinypic.com/6eq9eg.jpg

5. Here is another wire, the blue wire goes down under the left(driver) side corner of the engine. I tried looking it was dirty/greasy, couldn't tell what it was.

6. Here is the warm up regulator with the black hose, and has a "T" conector, connecting itto the other hose. Is that "T" connector wih the hole supposed to be there??

If you guys can really help me out here, I really need the help!! I would really appreciate it!!!!

Thank you all!!!

Hi Billy, I know some of these....

1. Those two white connectors should be connected.

2. I think that connector is not used if you have a manual trans.

3. Those look like the wires that go to the diagnostic plug. The bare orange wire is the one you use to check the lambda system with a dwell meter.

4. I can check on that one in the morning. I think it goes in that general direction though.

5. That red/white wire is supposed to go down to the starter solenoid to bring +12V to the cold start valve circuit. I'm guessing your cold start valve doesn't work.

6. See the vacuum delay valve (the black cylinder with a white end that has vacuum hoses on either end)? The vacuum hose that is going down the top right corner of the picture is supposed to be connected to the T-hose. Do you have the vacuum hose diagram on your engine cover? Check that - it shows you how the vacuum hoses should be ran.

I can help you with all of these tomorrow if you have more questions. Car is in the garage and I'm not going out again tonight :-) Looks like you have a lot of straigtening out to do. How does the car run? I'm guessing not very good with all the broken wires and vacuum leaks!

Here are a few more pictures!



This is an alarm system one of the previous owners put in. The Black wire form the fuse turns into the Red wire, which runs under the fuse box into those wires there. There is a Grey wire, BLue & Green wire. What do I do in with these?

Here is the alarm unit. You guys suggest I just cut off the wires and get rid of it?? No alarm ever worked when I got the car.

This Box here?

What is this device??

Everything seems correct here?

http://i56.tinypic.com/fnzbr5.jpg



Here is the door lock upgrade from Toby! Is that the correct placeto put he yellow wire?

I also was working almost all day trying to get the Wings-A-Loft together! No luck at all with that! :-(

Goonna start a new seperate thread for the wings-a-loft! Look out for it!!

#4 should be going to your Oil Sender unit? I would shrink wrap and solder it correctly.

I would strongly suggest your remove the old door alarm system. Most, that I have seen, were not installed properly. I would gut it. I had an after market looking alarm system in my car, and it caused me a mess of headaches.

+1 with Ryan.

Dubious PO work should be removed IMO. It seems the vast majority is unsafe and makes the car less reliable. I'd rewire the car back to stock configuration and troubleshoot from there.

The "alarm unit" in the second picture above looks like an old 12V lead acid battery!

Billy,

I tried posting this correction the other day, but it might not have gone through. Anyway, I made a mistake.

#2 - that connector hooks up to the connector that goes to the vacuum advance solenoid. It provides power to it. Since it's not plugged in, I'm guessing your vacuum advance doesn't work.

#1 - Most people have all three of those connectors in a 'block' - they attach together like one big piece. Looks like you are OK there - the one connector doesn't go anywhere on manual trans cars.

#4 is right. That's how the harness is normally ran. Some people have rerouted it to go under the intake manifold. Not sure if that's a good idea because it can get quite hot down there!

If you are talking about the white connector above the W-pipe, that's not correct. I think it has something to do with auto trans stuff. I have a manual so mine isn't used. I heard the explanation long time ago, don't remember, but I am positive it's not used on MT cars.

Billy,

The big black box sitting behind the driver's seat on the shelf that says Bosch on it and has two big white plug - that's the idle speed ECU. It tells the idle motor how to operate.

The picture below it, of the silver box pointing downward with the wide black connector on it, that is the Lambda ECU. It takes readings from the Lambda/O2 sensor, determines how much oxygen is in the exhaust, figured out if the car is running rich or lean, and then adjusts the frequency valve duty cycle to compensate.

Both boxes are OEM and I don't see anything odd about those pics.

So here are more pictures of screwed up wiring!! One of the previous owners had some alarm system on the car along with a back up battery. Wiring is all over the place, tapped into dome lights, fuse box, engine compartment. I gotta figure all this out!! CRAZY! Along with the fuel pump and rest!!
Who ever did all this really screwed with the car!!!! :angry:

1. This is a 12V lead acid battery, to the left of the Lamda ECU. Part of the alarm system which is directly under, in the driver side compartment.
http://i55.tinypic.com/v83rtl.jpg

2. Here is the alarm unit. Damn you!!! :mad: Wires all over the place, tapped into the front under the dash, the dome lights, fuse area, engine area.
http://i51.tinypic.com/20sj2ms.jpg

3. Wire from the alarm system going to engine, then in the engine, wires are all cut up, very long red and black wires all tied up and lead to no where. One wire tapped into black wire which goes to the metal box right on top to the left
http://i56.tinypic.com/25rh2ip.jpg
http://i56.tinypic.com/2r5un1y.jpg

4. DO these wires look as if they belong there, or is it part of the alarm system?? The colored wires with the Blue connector
http://i55.tinypic.com/oi509i.jpg

5. Alarm Wire, driver side foot well. Red wire from alarm connected to LH dome light switch, and to a grey wire which goes to passenger side dome light switch. I think I will leave the grey wire so I can connect the wire for the Wings-A-Loft system from thge driver side!
http://i51.tinypic.com/21o4m6h.jpg
http://i52.tinypic.com/e9u1vq.jpg

6. Here is something else. A Red/Brown wire tapped into by a brown which goes into I guess a fuse then out a Green wire. Couldn't really see where the Green wire went.
http://i53.tinypic.com/333fhnm.jpg

7. Here are more pictures of the fuel pump, found the stock wire and plug.
http://i55.tinypic.com/20icgmu.jpg

8. Black wire on the plug is cut off as well as the Beige/brown and has a yellow cap on it. The fuel sender unit plug, Red and Orange are plugged to the sender unit, there is a black on not connected to anything. Any idea??

Really hope you guys can help me with this one!! I have a project with the car itself fixing all the fail parts, worn out parts, ect... Now I gotta fix all this mess from the previous person!! Sucks!!

I always love the frequent inappropriate use of electrical "wire nuts" in places they really shouldn't be. There are so many better ways to terminate and tap into electrical wiring. Using wire nuts you're just looking for trouble and it looks amateurish: corrosion, loose connections, etc. Personally, I always solder, use a lineman's splice, and shrink wrap connections whenever possible.

Those pics just make me cringe. Kudos to you for taking your time and restoring the wiring first. Yes it is a huge pain in the ass, but just keep positive and think about you will have a car you can ACTUALLY diagnose after it's all done!

Notifier is right... wire nuts are a huge cringe. I also can't stand seeing tons of butt splicers and vampire clips. I can understand one or two... but damn. My car had some kind of alarm system installed with a kill switch. Found the kill switch in a VERY hard to get to spot... im actually going to make that live again. All the old alarm wiring (which was actually cheap speaker wire!) was ripped out, all butt splicers and vamp clips removed, soldered, and shrink wrapped. It was a fun project, and believe it or not, little things started coming on, battery drains went away, lights worked! It was like Christmas!

You're on a good path. Just watch that soldering gun near that fuel tank! :)

Billy, are there any other DeLorean owners in your area? It will be a lot easier to have a stock car to compare to instead of taking photos of stuff. It's hard for us to poke and prod with a photo. i think your best bet is finding another owner you can compare with in person. Your wiring is definitely hacked up.

I've seen through the forums and youtube owners who live in NY, but kinda far from me. I live in Queens. No one really close. PJ Grady is about an hour drive. And this car won't be really moving anymore till I correct all this wiring mess, along with the fuel pump wiring.

I know, sometimes its hard to tell from pictures.

As bad as hacked up wiring looks it is not all that hard to figure out how to dissect out the non-original stuff and fix up the mess. I also cringe when I see wire nuts, it is a BIG indicator that the last person didn't know what they were doing and the WHOLE wiring system in the car should be thoroughly inspected and repaired. To do proper repairs things should be soldered and either taped up or covered with heat-shrink tubing. You really can't do any work properly on the electrical system till you have removed all of the "alien" components.

I had several butt splicers on the brown wires running behind the rear carpet board and through the relay compartment. I think at some point some wires melted and butt splicers were used to make the repairs. I had to remove lots of electrical tape to see what had went on. I really dislike electrical tape because when it gets old, it leaves behind a sticky mess. After I soldered and heat shrink wrapped the wires, I decided to rewrap my wires with silicone tape. I really like that stuff, no sticky mess. You just need to be careful when you apply it, because it sticks to itself really good.

As far as the fuel pump stock harness, this is the correct below??

This is stock wire and plug??
http://i55.tinypic.com/20icgmu.jpg

Black wire on the plug is cut off as well as the Beige/brown and has a yellow cap on it. The fuel sender unit plug, Red and Orange or yellow are plugged to the sender unit, there is a black on not connected to anything. Any idea??

Yup, that's a stock plug. W/P is 12v, black is ground. Normally they run into your front harness. What's left of the originals are probably dangling up by your fans.

The black wire that doesn't seem connected to anything (if I'm seeing it right) is a ground at the filler cap to avoid sparks.

I'm about 45 mins away from you. My cars wiring is fairly stock and clean. The best I can offer you is if you want to use my car for a comparison your welcome to it. My car never had an alarm in it and I have found several disconnected connectors, but I was told to leave it alone if everything is working which seems to be the case.

On a manual trans car, I can only think of three things that appear to be unplugged - the diagnostics plug and the connector on top of the W-pipe (the white/black connector that seems to missing a piece). Also the hot-start relay plug.

There shouldn't be 'several' disconnected connectors.

I know about the wire ontop the W-pipe, a couple people had mentioned it to me. Diagnostics plug, and hot start relay, where would I find those?? I havent seen and relays misisng in my fuse/relay section, except the tach/fuel relay.

Ive done this myself with a friend here locally MANY times. It really does help..except if the types of transmissions are different.
