ABY Wiring Harness Help/Identification

[hermanio]

thanks for you help, the wire colors are Red-black and Red-green

[Mr.Crossfire]

Many thanks for this guide! Just got my 90q started & running for the first time with AAN engine. I made a good use of this manual, I guess I would not be this far without it.

those are identified in the document made by Paul

Those go to the "secondary" engine harness and have connections for the MFTS, oil pressure, after run pump, ect..

[marson]

ok thanks, i´ve found the document. do i need this when i have a NG coupe without bordcomputer.

[Ruffiano]

yes you need it.

Hi all,

Looking at the schemes, I feel like t5h is not present in 3b cars. I notice it because I cannot find it in my car, and in schemes I always find " *cars from 10/93"

Am I correct?

Bump to an old thread. I've been marking up my ABY engine loom and came across this off red relay plate that doesn't appear to be mentioned in this thread, but is part of my ABY loom. It is part of the fuse board cluster, connections are:

Pin 2 - black/green x 2
Pin4 - black/green
Pin 6 - brown/blue
Pin 8 - black/grey





Can anyone tell me what this is for?

Cheers
Alex

Yearly bump! Can anyone tell me what this is red plug is for?

Set your MM to ohms and stick one probe in a socket on the connector and try and find continuity somewhere else! The wire colours should help to identify where to stick the other probe. Make a list of what goes where and it might become apparent! Bit boring but shouldn't take a year to complete. That is if you want to find out.

Or look at posts 86 & 87 for a possible clue!

OK so it is the connector for the anti-theft relay. Does anyone have a wiring diagram for this circuit?
Can I just leave it unplugged, or do I need a relay and if so what number it is and what triggers it?

[twoqu]

There is a diagram in the RS2 Motronic workshop manual on Mike's S2 site but it does not have the same colour wiring.
I'm not saying it is, but if you know you have an immo loom then its a possibility.
Not sure about the other questions. Try me again in a year unless anyone else pipes up!

[Error404]

Thanks I'll take a look at that, as Paul didn't publish the details on S2Central.

My ECU is non-immob so as long as the relay can be by-passed its no problem

I finally got around to sorting this out today, its very simple actually. If anyone needs to know how drop me a PM
