OK so heres the next round.
1. Above the oil filter there appears to be a sender, the bit at middle right with a white ring, it doesnt look like anything can connect to it. what is it and should there be a wire?
2. Although i haven't managed to wire up the cold start valve i always noticed that i have two plugs in this area, one of which can barely reach. the blue one was the one that was always plugged in, the other was never plugged into anything, any idea what its for?
3. not important but i am having to fabricate stuff as my new looms dont have everything my old looms did... this additional relay was in my old box but was not wired to anything when i got the car back... i looked up the part number which came back as a compressor relay! what else could it have been for?
