Under bonnet driver side.... Fuse box has lots of plugs
What part of loom is this and where does it go.????

Missing off my car and been trying to sort out bits but don't know if it's engine loom or for other things.!

Cheers chris

Its the side where it comes from the fuse box inside the car  ... its mostly  engine loom mate wich you can unplug like when removing engine etc

Next question is has anyone got a spare they wanna sell..???
