I have a erst 1897 that is fresh from the body shop the car is running a st170 turbo engine with cosworth management now the problem is the loom in the car is really bad condition will a mk4 1.3 loom work with the mfi fuel pump I no I will lose the heated front screen and electric mirrors if I change the complete loom ?

 

Add new wiring from the cosworth engine loom to the fuel pump.

I believe the heated screen and mirrors are additional looms so you might be able to swap them over.

 

Yeah think you right about adding it on to the loom I've just took the dash out the 1.3 escort there looks like spare plugs and factory wrapped wires stored in. The a pillar
