I had rebuilt the spare head that I had and recently fitted. Engine started up and ran smoothly and quietly but as I was packing my tools up to take it for a spin, the car cut out and wouldn't restart.
Plugged in OpCom and Electronic Throttle Control Malfunction error code was present. I previously came across this code and changing to the engine loom solved the problem.
I tried AutoVaux to get a price for a new loom but they have come back with 5 different parts. Apparently it depends on the indent on the harness but I cant seem to match any of the listed indents to the codes on the harness.

Can anyone tell me what the correct wiring harness that i require? Also what will the difference be between the 5 listed parts from AutoVaux?
