I wonder now just how many DeLoreans have been converted to MegaSquirt, let alone EFI. I was trying to track EFI conversions, but now maybe I need to track MS as well.

Hi guys, I have some news to share with you. I finally (almost) completed the internal wirings for the EFI set-up.
the wirings arrangement can be seen in this pdf MS WIRING Model (1).pdf
I have wired 3 relays: LC-2, MS and injectors, fuel pump. all the wires are fused through this useful fuse box which give me +12V, +12V on key and a common ground: http://www.ripca.com/nl_en/fuses-hol...ekeringen.html
I will try to explain each circuits, and I have a couple of questions for you.
I found a male plug for the rpm relay socket from which I use the green wire from fuse 1 to feed the "+12V on key" fuse box side, brown wire from fuse 7 to feed the fuel pump relay, white/purple wire to feed the fuel pump and white slate wire for the tach signal to the MS. http://imagizer.imageshack.us/v2/800...540/aFrduO.jpg
Since fuse 7 has 2 different wire gauges from factory I routed a new 12AWG brown wire from the fuse to the the rpm relay socket, as the original lambda relay is not needed.
I routed a new white/purple wire from the relay to the rpm socket but I found the white/purple wire only in 14AWG: do you think it will be a problem?
should I change the amperage of fuse 7? now it feeds just the fuel pump, maybe a 15amp fuse would be enough. the 10amp fuse for fuse 1 sounds appropriate.
I am wondering also about the fuse amperage to pin 86, 1amp should be adequate.
about the "main relay", it is feeded by a 20amp fuse from the "+12V" side of the fuse box. maybe I can reduce fuse amperage to 15amp. the relay's 87 pin goes to another fuse box (this one http://www.ripca.com/nl_en/fuses-hol...et-deksel.html) which feeds the MS, both injectors banks and the knocksense module (this one will have a 1amp fuse since it draws 10 mA). all the wires used are 14AWG.
the LC-2 relay is wired as per the instructions in the manual at page 4 http://www.innovatemotorsports.com/s...C-2_Manual.pdf
likewise the AFR gauge is wired as per these instructions http://www.innovatemotorsports.com/s...ual%28B%29.pdf
the white wire needs to be connected to a dash light wire, I think I'm gonna wire it to the red/orange - red/brown wire at the A/C panel relay (I connected them as per the A/C light mod) http://imagizer.imageshack.us/v2/800...673/uNU2Q6.jpg
lastly, I have the fuse box main ground and +12V connected to the ground and +12V spot on the firewall (driver side) but possibly I'd like to connect them directly to the battery but it seems that the battery compartment is sealed and there is no way to route the wires to the upper electrical tray (unless I am missing a free spot). so I should have to drill the "upper closing panel" or (mad idea) to route both wires outside of the cabin from the battery wires grommets and reintroduce them through the parking cables grommets..
Let me what you think about all this stuff!
Many thanks

You really overkill the wiring with that heavy gauge wire on signal lines but that's not a bad thing if you already have the wire in stock. I pretty much us 16 AWG wire because that is what I have and it fits most all of the crimp terminals. If I need a large current circuit I can double up on the wire.
Fuses......As you probably have seen, I've been running testing on fuses. The rating of a fuse is what it can carry for current without blowing open. Fuses are not really a device to protect electronics from to much load since fuses can take hours to blow open running a little over the rated current. Fuses do protect your wiring from short circuits very nicely since they blow open quickly then the currents are at least two times the rated currents. Just remember using lower current ratings, the fuse resistance (voltage drop) goes up with lower current ratings. So your fuse will produce more heat if that's something your concerned about.

Hello guys,
just a quick question, what should I do with the "metal sleeve" from the MS screened cable (with pin cables #1, 24, 26) ? http://www.diyautotune.com/images/ms...s/mswiring.png
I am using a VR sensor which has 2 cables, and I don't know if I should leave the metal sleeve (pin #2) as it is, ground it to the block or crimp it with the VR ground wire..
Cheers

the "shield" goes to the MS connector (and so to the ECU), pin #2 on this wiring scheme: http://www.diyautotune.com/images/ms...s/mswiring.png

I don't remember what pin was used since I have a relay board but the shield was grounded to the MS via that board. The shield ended a few inches short of the connector to the sensor on the other end. Keep in mind to run your shielded wire away from any high current wiring such as sparkplug wires etc and watch for sharp bends/edges. I ran my shielded wire separate and away from any other wiring, it also enters the car from the engine compartment separately from the rest of the wiring.
Edit: After looking at the MS3X/3.57 manual, it appears my VR sensor wire's shield is wired to Pin #1-2 of the MS ECU. Also page #70 of that manual shows a small diagram and says to use sensor ground to ground the shield of the shielded wire. Check that page out for more info.
