Oil pressure wire question + unknown wires

[Nibs83]

Hi folks, just a quick query, does this wire come off the same part of the loom as the lambda sensor, as I'm not sure as there is another one for the back of the starter motor that comes from the earth wire for the starter.. It's been that long and I've forgotten.

Also I've found 3 wires with a unknown destination red and white and a separate pink one. I think, it's at the alternator side of things, they are both spade connectors, pink one has been cut, it's not the earth for the alternator, it's nothing to do with the fog light wiring loom, nothing to do with the horn or the round sensor that goes clips into the guard.
Any ideas? I could post a few images if nobody knows. Them seem to want to go down towards the wheels through a very small gap.

Cheers
andy.

Get some pics up.
The pink one sounds like brake pad wear sensor.

Yes, think your right about that one as there is one on either side of car, both been cut. Cheers.

And the red and white with spade connectors sounds like fan switch in rad.
