e30 m52 ..... so close .......

[bryE30]

Hi so i just need a tiny bit of help to get my e30 m52 project back on the road.

i need to fit the e30 brown temp sender into the cylinder head? it is a black 4 pin one at the moment, how is the brown one wired to the temp gauge?

with the oil seperator i just blocked off the drain for now but if i remove the unit how do i finish it?

there was a charcoal canister and also the flexible hose that goes to the valve on the e36 exhaust , i literally just disconnected these and left it at that..... will this be ok?

many thanks
