HELP,
Well after swaping total loom and instrument/motor PF mot/type with digifant from mk2 and put it in mk1 , i have big problems but now i only need help on this:
Well have been at it since 9 this morning, found at last the reason for the glow of turn light/fuel in instrument , fuelpump buzzing and the black/blue having power on when ignitions off. Pulled out the white loom stick F on CE2 fusebox. When off everything works? The lomm that has thick a thick red/black- blu/black-green/red-thin red/black and brown all go to engine compartmen. Dont understand why it affects instrument and so on, could it be the fuse board thats brokken.
Since its not atached to anything in engine whers the fault comming from?
I havent yet put motor in due to i can be sure all wires and spliced mk1swiches to mk2 loom for faults!
