Pin Outs! i need them

[RickSloan]

I searched and found nothing helpful

can anyone get me the pin outs?

i have a 1985 325e chassi

and a 1987 635csi harness

all i need is the wiring to turn the key so if anyone can help me that would be awesome!!!

[RickSloan]

also the 635csi harness was an automatic, the car is a manual. are their any other wires i need to cut or get rid of or switch?

[RickSloan]

anyone?????? i really need this, can anyone tell me a place where i can maybe get it myself???

I'm willing to pay the first person to get it to me!

so please someone help!

Dunno if this will help, and im not after your money but I'm using this (but I'm going through the harness myself and double checking using this website)

Google what you want and spend some time going through the shit, you will more than likely find the pin outs and wiring colours in PDF format. Thats what I did with these two websites (though I'm after a 1989 e34 535 wiring diagram and 1984 e30 323i diagram):

that may be a bit of a pain...I don't know if the 85 e30 had the motronic 1.0 or 1.1 system...the e24 probably has the 1.1...and w the e24 being an auto harness you are going to have a bit of wiring to remove...so save yourself a headache u may wanna try to find an 87 325i manual harness..that is the route I'm going. then you'd only have to lengthen a couple wires instead of rewiring it all up.

Those wiring schematics can be found on www.e30.de ;)

they are all in german!

according to E30.de both re motronic 1.0 but the 325e is basic and the 635csi is advanced

Yes, and it's German car... Use translator tools, there're plenty of them on internet ;)

i know i know, i actually have them on my computer... just alot of translating... but hell this swap has already been a ton of work whats a little more right...

ok under hood wiring aside cause i think i have it figured out... any thoughts on the wires by the ecu??? like the ones that power the ECU? any thoughts would help, i know i just need to decipher those diagrams but im seeing if anyone knows off hand

thanks in advance

Are you talking about the C103 / C104? Generally 3,4, or 5 wires right near the ECU? Other than those you shouldn't need to touch anything else near the ECU, all of the splicing happens at the fuse box connection - C101.

[RickSloan]

yes i am speaking of those, i believe i have a 3 or 4 wire one on the harness and maybe one other one, and a 3 wire on in the car

Last weekend I swapped an '85 chassis wiring harness and fuse box into my '83 635CSi euro with the early motronic (early 325e, 528e, 533i equivalent) and to get it started I had to jump the center terminal of the main relay to the positive terminal on the coil. I had to do that because my engine harness has 3 wires and the chassis harness has 4. Keep that in mind when you are doing your wiring... At the very least it will allow you to get it fired up and start sorting things out.

If it's 3-wire connector (yellow - consumption, black - tacho, green - power for ECU). Some models have only two wires (i think only in facelifts, they've something to do with air conditioning).

In M30, the ECU power goes through engine wiring harness, not directly to the ECU as in M20. No idea how to get consumption-gauge to work. Tacho is direct plug'n'play.
