Any idea where these wires go? 85 325e

Good morning fam!

I just picked up my first early model coupe yesterday, 325e, after owning three late model convertibles.

I'm chasing down an idle issue caused by Fuse #9 keeps blowing instantly. I've been chasing wires to check my ground connections and have came across multiple plugs missing. If anyone has an idea of where they go before buying a new harness, I would appreciate it.

Pic 4 is for OBC gong. Early cars had them right in front of the fuse box.

Pic 3 I think is for factory test equipment...not used.

Pic 1 There is a sensor on e's right above where the main harness goes through the firewall. From memory I believe it's 2 wire not 3 so someone else chime in.

Thanks. I ended up buying a new harness and am in the process of swapping over. Good to know what those plugs do.

The last photo jumps out at me as being the water level sensor in the radiator, assuming in the background is a much longer lead. But i think you only have this if you have the check panel above your rear view mirror.
