c101 and x20 wire diagram (e30 M50 adapter)

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.

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:

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.

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..

Oh mint haha so im not as dumb as i thought :-D sweet ill figure out how to wire up my RPM wire, fuel consumption wire and service reset wire. Will let you know how I get on, will be a few weeks cause my heads not gonne be rebuilt till the 27th! :(

That diagram couldn't be simpler, you read it correctly. It' just doesn't apply to your car.

Not really clear on how that diagram works? So the Engine Input Speed wire goes through plugs C103 -> C235 -> C104 to get to the ECU? My E30 is an 88... facelift so in theory if its the same as a USA one it wont have the C104.

If your is 87 then it is NOT in C104. Take a look at this - C104 pin 1:

[EtaSport]

So I would still need to hook up my rpm signal wire that goes to the rev counter right? I would just run a wire from pin 20 on the E34 X20 connector to the rev counter wire in the back of the speedo cluster correct?

Luke

late model cars with no c104 had the tach signal in the c101.

Ha ha if i only had money to blow
i thought about it but when your a poor college kid trying to do this beside your garage yah

It really is worth it. Use some of that student loan money or pick up a part time job, you could have the $ to get one in a week.
