    CEL Check Engine FYI for 87 and earlier cars

    Sorry for the redundant title, just to make it easier to find for guys searching.

    I was wondering why my car wasn't throwing any codes even when it was stumbling at WOT, surely the knock sensors would be crying bloody murder... Went to see if my CEL is on with ignition on, nope. I thought I fuxored the wiring somewhere, pulled my adapter, checked it over and everything was right. Then I looked and my car harness doesn't fucking have a pin 12. The ghetto eta (and possibly early 325i and 318i) don't have code monitoring from the DME.

    So I routed a wire through the cruise control firewall grommet, from my adapter (E36 pin 8, grey), to the white/black wire on the C1 connector of the cluster (C1 is the farthest one on the radio side). This is the wire that the check control grounds to light up the CEL. Bingo, CEL works, along with the stomp test and everything.

    Nicely done D. Euro cars (at least my '88) don't have it either, I just connect a test light onto the pin 8 to check when the car starts running funny... But I should run the wire in like you did. Sounds like a perfect fix!
