Chassis harnes-engine harness connector pinout
 

I'm quite far into installing an AP1 in my 1973 BMW 2002tii and I'm building the wiring harness. Can anybody provide me with a pinout of the light blue plug that connects the engine harness to the chassis harness? I've identified all but 6 wires on the bottom row. Help is much appreciated.

Regards,

You need the pin out for c101(blue connector) which can be found, kind of, on this forum. Google or search "s2000 c101 pin out". I'm doing a f2k swap so I've looked it up but haven't completed it yet. From what I've gathered so far there is only a handful of wires really needed.

I believe there is a build thread on s2ki with a f20/22 into a Datsun with a description of what the owner used for c101. Might be worth looking that up.

Good luck.

Thanks for the tip, but I had googled it, but found very little. I've actually identified all but 2 wires on the light blue, 2-row connector(which I'm not sure is C101, google doesn't show C101 looking like the plug in question), bottom row, 5th from the LH side of the plug, the Yellow/Red trace and 2 gray dots, and the 7th from the LH side, Yellow with single Gray dot. If anybody knows what these are, I'd be appreciative. I'm quite sure I will not need them for the motor to run on the AEM, but I'm curious. Much thanks in advance.

This is the correct s2000 C101 connector from the Electrical Troubleshooting manual, and the two wires
you asked about appear to be in the positions you mentioned, so hopefully this is what you need.

Found this within 5 seconds... and it might possibly be the greatest wiring harness post to the s2000 community

His hand written pin out is what you need.

I had found that too, but I was initially skeptical because there seemed to be a bit of inconsistency at first, but then I realized he was reading the plug from the opposite end. At this point, I'm pretty close to making noises in the garage. Thanks for all the help guys(gals too, maybe). On another note, just pouring through this forum for information makes me want to buy a car that came with an F20 it, you guys seems like a pretty good crowd.
