red/white
blue = temp
blue/red thick = fuel pump
blue/red thin = speed sender
black/red = starter
black/brown
brown/blue - ecu light
brown/white ecu diag
brown/yellow = evu diag
green = tacho
black/green
i think the unknowns are autobox and air con
hmm
so where does it get its main +ve feed from?
also the red/black? the corsa has a seperate loom for the starter which wev conected, and we cant find the other end to this red/black on the engine loom :roll:

black sleved wire direct to battery (if it's a cav/cally loom)
ye the big f.off thick wire :D
ye thats conected to +ve on battery via a fuse.
anyways of testing if ECU is powering up properly
more to the point
what colour is the switched live on the 20xe loom? cant see any black wires that usualy give the game away :oops:
