ALMOST done.. but what about these?

pic3.. the connecter might be your charcoal canister valve connecter. i think its hard to tell where the wiring is coming from in the photo

First off, what year harness are you using? is this m52 to OBD1?


Pic 1 looks right, the cable should connect there and then splits into alternator and starter.

Pic 2 looks like it would probably go to the starter, what color are the wires? (they should be uncovered at some point, possibly near the rubber covering)

Pic 3 where does that cable route to? Is your MAF plugged up?

It's a m52 engine with obd1 95 m3 harness in a 1989 325is e30.

K. Pic 1 sounds right. On pick 2, I'll double check the colors, but why the starter?? I don't think they would even reach the starter. Maybe alternator ground? I'll get back to you on the colors. On pic 3 the MAF IS plugged in, so its not that. I don't know exactly where that cable routes to as it is VERY long... it could just about go anywhere.
I bought the harness from the forums... is it possible someone gave me the harness from an automatic car and not a manual? and that those extra cables are for the automatic car??? I can't I.D. these so that's my guess. (arggh!) Either that or maybe they are for the o2 sensor and something? Currently I don't the o2 sensor hooked up anywhere... I still haven't picked up an OBD1 sensor and I havn't heard you can use the OBD2 ones; does it matter? I don't see anywhere else where the o2 sensor would connect to the harness.

I think this is my 5th post saying "just finishing up".. but as you can see I'm almost there.

For starts.. yes I'm thoroughly looking through the 700 page manual trying to make sense of a lot of the diagrams + even find what I'm looking for…

I'm a little confused on the positive and ground connections. On the e36 harness, passenger side, there are 2 main positive plugs and 1 negative cable right? I took a picture to maybe help identify them. Can someone confirm this is correct? EDIT: The positive lead coming from the passenger side splits off one into the starter and the other would go to the e36 fuse box, but in this case isn't used.

^ OR if its easier, maybe could some just explain the layout of the positive and grounds?

On the same note of that, I've got two unconnected "grounds?" on the driver's side down by the alternator/oil pan. EDIT: Still haven't verified these...


Oh and then there are these I still don't know about… (EDIT SEE BELOW FOR ANSWER)

EDIT: Confirmed this is for the O2 sensor (clipped wire) and the reverse light.

I think that wraps it up and then I'm ready to start the car! Thanks again for your help guys!
