unknown plugs on M60 loom

[Driftben]

i have traced the wires from the auto loom and have now cut most of the auto loom out, i just have a couple questions about some plugs and a wire.


there is a black/brown wire which goes to the loom plug which i have cut but i am unsure if its needed?


not sure what this plug does?


also i have removed the aircon but now i need a AUX belt which doesnt include this? is there a part number of one which is smaller?

thanks

On what pin was the black/brown wire?

The plug could possibly be one of the asc throttle body.

Normally there is a short aux belt for the aircon and a larger for all other parts. Your belt is not correctly installed, but it is the right one.

thanks mars and willnz, the belt is all good but still chuffling through the wiring which is amost done now.
just have one more queiry, as i have now cut the auto loom out where is the black/yellow wire that i need to link from the relay to give the ecu the start signal?

thanks
