I've just bought a FRST engibe to fit in my MK5 fiesta, im an apprentice mechanic so im capable of mounting the engine and all the cooling system etc but my knowledge of wiring is crap because i have no experiance of major wiring work so im after afew pointers on what exactally i need to do in regards to wiring the engine in??
I was thinking about running the mk5 loom for the lights etc and a second ecu to run the engine but im not 100% what would be best.

Anybody that can give me any pointer would be greatly appreciated

cheers
