I'm in the middle of installing my Sierra based Loom,I have come across a few wires that I'm not to sure off,I was wondering if someone could shed some light on the subject for me !!

First off all...

Wiper Motor
Black/Purple - parking supply,where does this go ??
Brown/White - Parking brake ??

Warning Lights.....
Brown/Green & Black.. Why is there 2 wires going to the oil warning light when there is only 1 at the engine spur side of loom ???
Do I just splice these both together and connect to oil light on dash ??


Cheers Guys

Oil light I would guess (I'm at work at the moment) that one wire at light goes to the switch via the engine loom (the colours should correspond) while the other goes to ignition-controlled supply via the fuse box.

+--- oxo------light -------switch on block

For he wiper motor, I would have to have a look at the destructions tomorrow.
