i have been stuck for the last few days getting hold of a piece of loom, and need a few things clarifying...

The loom i need is for a 04 2.2 astra coupe. It runs from the ECU to the cooling fans, air con etc.

The car had been in an accident, and this loom was removed. I have tried many breakers with no luck, or some say i need a code. Where could i find this loom code?

Also will the cooling loom fit from any other engine size loom?Are they all the same?
