c101 and x20 wire diagram (e30 M50 adapter)

If they were on wedophones web site then I have them at home and will email them to you when get back from work..

I was wondering if somone happens to have a table of all the wires needed to connect an S50 OBDI harness to an E30 318is, need to go back and check if the guy that sent it to me did it right...There is a lot of reading here...sorry if I missed something..

find an etm and the instructions are in this thread. it takes some time, and most people who have done the swap have looked up the wiring for themselves. this way if you run into problems you have a much better understanding of how its supposed to work as opposed to someone just giving you pin charts that you're not even sure about.

ok I was looking at some of the diagrams from here, one from the S50 to E30 M3 swap table (used the info on the colors for the S50 harness) and used the diagram from the C101 connector for the M20 that is on the first page of the thread. It appears that all the pins are in the right places. :crazy:

good add to the thread...

Did you even read the link?? That site is for M30 swaps and doesn't really provide anything new other than part #'s for the engine side C101 connector which can be found at realeom.com.

Just read this thread, boy it looks like I am in for some fun with an 84 318i wiring...

Guys on my 325es I can't get power to my diagnostic port unless pin 22 on the E36 plug is hooked up to power. What did you guys run this to?

Thanks

[EtaSport]

Doesnt sound too right, just looking over the thread real quick, pin 22 was used for reverse input. What is the wire color?

[Beej '86 325es]

It's a green/white wire.
On the chart Mike B. did it says it's "Reversing Light Switch/Datalink (Voltage-Ignition Switch in run/start).
It looks like a lot of this info in the thread is for a 325i, and I have a 325es, I'm wondering if I'm missing something basic. Fortunately so far at least all of the wire colors are matching up.

[EtaSport]

Okay, well perhaps I was going off of the start-input function of that wire, because the colors indicate that it should get 12 volts from the ignition switch. There should be two green wires on the e30 side, and it should go to those wires. The only real difference between the i and e wiring is the lack of a few wires on the e c101, and the fact that the e uses the c104 for three wires. Thats the way I look at it, and ALL of my functions operate correctly. (just need to run my wires for the oil level).
