Any chance I could get your number rubjonny? I should have the wiring loom from the previous mk2 gti it was installed in so its more a case of plug and play hopefully!
If thats the case and the engine was working then its a piss o piece mate. I've just finished my second conversion in 3 days from start to finish!

(Did need to work through the night though!)
Whats your post code? PM Me.
