E30 Zone

Got a loom which has a couple bits cut off, Annoying because I don't have anything to compare it to,

It's from an e36 m52b28 - 1 plug was blantantly cut off and sitting in the bottom of the box it was sent to me in. 2 wires match, but the 3rd is a white/red but the plug has white/red with yellow dots. Is it safe to assume it came from here? Seems like it is, just worried on colour difference.


Second is a 2 wire one , Green/white and Blue/Yellow. On the section coming under the intake mani, Any idea what this is from?


Lastly is the main relay I guess which is on the piece of loom just before the ECU plug. What kind of relay is required here?

Pics;

The two wire is for the reverse light switch and is not needed for an E30
The three wire, the Red/White wire is obviously different so cant say for sure but due to the length it does look suspiciously like the ICV wiring.
The relay is for ignition feed to the coil harness, standard green E36 relay in here

Sweet 2 sorted then, Relay fitted and will ignore the cut reverse light wiring.

The other though, If I join it - Can anyone confirm the ICV (If it is ICV) plug is:

Pin 1 - White/Green
Pin 2 - Red/White (with yellow dots or not?) - Maybe he chucked this plug in from something else
Pin 3 - White/Yellow

Pins 1,3 match the only issue is the middle one so I think it should be okay?
