last couple wires and plugs... halpp

[ScHpAnKy]

having trouble with the last couple plugs, I tried to label as much as I could based on the diagrams, but I want to verify the last couple to make sure they're labeled correctly... or simply finding out what they are.

Car is a '88 325iS, engine is a '92 m50nv


First up are these gems on the passenger's side... what are they? Which are power, grounds, where are they supposed to attach?


I didn't have time to trace these back last night, #4 looks like it's supposed to be attached to the terminal on the passenger side firewall, the other looks like a starter power terminal or similar... but if that's the case there's like 5 starter wires for two posts which can't be correct...


relays... I'm pretty sure I found out that the blue one (#7) is the fuel pump, right? What are the other two?


Two from the driver's side... #9 I have as yet another starter power(???) cable...

#10 is labelled as a fuse box cable, but I don't see where to plug this connector anywhere into the fuse box... do I cut the connector and splice it somewhere into the fuse box? Or does it recieve power and need to splice it with something providing power?



I don't have my booster hooked up yet, but I'm pretty sure this little guy goes to the reservoir?

As for the starter, there was alot on mine but removed the one of the e36 wires and used the e30. IIRC, I have a total of 4 goint to the starter. Have you traced the wire from the alt to the starter? Im sure by the time I reference mine, fellow r3vers will reply back.

I'm a little confused... bear with me, here...

hmm, I could have sworn the altenator had it's own power and ground off of the harness? I swear that there was a cable that matched the rear plastic bit off the altenator with power and ground already in it.

Which wire did you remove/where? I read in some thread that it was easier to yank a couple wires out of the harness and instead use the e30 ones... but I don't understand the differences in powering of the components to know which ones to plug in and what to remove :(

It took me a bit to sort out the wires for this part too. IIRC, your #2 is what I removed. the other end might have 2 thick wires at the end of it...that whole wire, i removed from the harness.

You can see the 2 reds on the drivers side...I pulled that out.

on 1 and 3, peel back the rubber if brown there ground. if red, connect to firewall

4 goes to terminal on firewall

6-7-8 are relays. them them chilling somewhere

5 and 9 should be the same cable, it goes from starter to alternator

10 - 12 v power. connect to firewall
