^Chart is wrong.

maybe I'm having a brain fart but why are you cutting the wires going into the C101 from the right hand side in this picture???
are you splicing the X20 in here rather than modify the engine harness??

yeah, I've never seen anyone cut into the body harness. Man, that must have sucked. it's way easier to modify the engine harness on a table..

Which part? please tell. I know at least the CEL is wrong now, but after a little help from LOLCANTTURN it runs. It turned out i just had the fuel lines switched. What a noob issue hahaha.

Please help me sort out the other stuff.

I wanted to swap the body side plug so that I can leave any e36 harness uncut whenever i swap anything with an x20. It also meant that i didn't have to destroy the good harness on the m42 engine.

awesome pin 6 pin 20 c101 to pin 22 of x20 . dual purpose.

@86325LSD and @nando - so I should literally U turn pin 6 into pin 20 on c101, and then splice in pin 22 on X20?

Btw, I have a late-'88 produced' 89 325i

Yes pin 20 needs 12v coming from the car side. So pin 6 or the other o2 sensor heater wire. Both supply 12v with ignition on.
