Ground/Power question

[Sirjustinderek]

Started to beautify my harness so took it out and got it modified to fit a early model (1986 325e). I seem to have an extra power line it seems?? Can't figure out where it goes. Any of you have pictures of your terminals and where they are grounded?? OBD 2 harness, s52 with m50 manifold.

Thanks in advance. I'll post a picture soon, it'll probably help.

I knew the answer to this about 6 months ago. I think it might go to the SAP? (Air pump). I honestly dont recall though. Either that or it went to power the fuse box separately. I honestly dont remember. Are you talking about a red +12v wire or a ground?

If you have an extra thick red power wire, it goes to the fuse box on the E36. You can reuse the E30 fuse box power and delete that one. Or vice-versa.

The ground coming from the body. I have the red one connected to the starter

give us a picture and I will tell you exactly what it is. I went through the same thing like a few weeks ago. I will help with a photo in response to yours :)

Hey I think I figured out the problem. I had the e36 box still connected and it was confusing the shit out of me. Tossed it and wired all to the power terminal on the passenger side firewall. However!, now it's not getting any fuel so won't start up. Turns over no problem. Pulled the fuel rail and nothing is coming from the injectors. Now what??

Fuel lines on backwards? EWS in the DME?

EWS delete. Didn't get to look at it today. Work was late
