Having some wiring difficulties, wondering if anyone can help.

[Link]

I am working on finding all the functions on the engine and body side of the c101 connector on my 1991 318i. This is what I have so far.



Im wondering what you guys think. I went and wrote down my exact color of wire to corresponding pin # so this is exact to my car. I can not seem to find what the rest are, other than what other people are saying in similar charts as mine, where they are unsure. Im looking for solid evidence. Any suggestions?

Why is it that every wire diagram and write up I read they have Pin #2 as having a wire and Pin # 3 as no connection, where on my car there is in fact a wire in pin # 2 but no wire in pin # 2. Any thoughts?

Hmm, not sure about that thread. Do I need to mess with the diagnostic connector on a s52 swap?

I have all the wire colors for the c101 on my exact car. Those I posted above ARE correct to my car. Every pin has been triple checked to make sure I have the colors correct.

Not too sure on the US side wiring.
Sorry.

pin 3 isn't connected to anything on any E30. it's always empty.
