Again, Ive tried searching but nothing comes back?
I have three issues trying to wire up in the drivers footwell, Ive used the plugs from the original corsa loom for.ease.
from the corsa plug I have two wires spare. solid black and the thick red, where do these go?
Also from the C20XE loom I have one wire spare. black/brown. whats this for? Other than these three wires everything was colour for colour.
Thanks in advance Andy.

So I've put on a new battery and borrowed a multimeter. I have no eml light on ignition. The thin black wire is a switched live for the ecu feed. I'm surprised no one could tell me this with the amount of c20xe corsa here?
The brown and black wire from the c20xe loom is a redundant wire for diagnostics (I think).
Still dont know what the thick red wire is for though? Any help?

Don't worry about red wire I have done same sort of conversion using origanl plugs so to not damage my loom and you will have a red wire hanging its not needed so just isolate that wire

you need the brown and black, thats an ecu diagnostics wire.
Take it you have converted a 1.2 16v or a 1.0 12v?
Thick red isnt used down in the foot well. there is a thick red with a trminal on the 2.0 loom that the loom + if it isnt there it will be on a 2 pin plug that at the end of the loom near battery. one red one black one constand live other igniton live. Near more info u2u me.
