if it's the same as english wire colours.......... (that's a BIG IF)
blue/white are main beams
red/white is ignition signal to the starter motor solenoid
don't know about brown/black
now on the e36 end, i have a fuel pump wire pin 13 that goes to a relay Siemens V23134-K59-X170 with 12.62-1735424 on it, on this realy i have 3 unconnected wires, a thick red, a thin red/white and a thin brown/green. where the fuel relay wire (pin13) goes into this realy, a thin green magenta comes out and goes to another relay Siemens V23134-K59-X222 with 61.36-8366600 on it, of this relay i have another 3 unconnected wires , a thin brown/green, a thin green and a thin red/white....
here's some guesses:
one of those relays is for the fuel pump? then the one with the red/white wire might be the starter solenoid relay?
green magenta is usually a fused 12V feed, does things like injectors and stuff. so there might be a relay for everything that's joined to that supply...
where have these wires come from, are they engine bay ones or behind the dash?
which are power feeds and which are signal in and signal out on the relays?
when I did the midget, I got away with not connecting all that much stuff, I can send you a wiring diagram that will probably not be any help if you like....
what's your loom situation - have you got the whole think out of the beemeer including lamp circuits and everything, 'cos i had all that in the midget already so only really had to wire the engine in...
'tis a fantastic project, the wiring was the bit i dreaded on mine.
