Ive got a mark 4 escort with xr3i running gear and i was just wondering has anyone got a wiring diagram or can they explain how to wire in the on board computer?
Cheers

 

best thing to do is get a ford escort haynes manual for sept 80 to sept 90, it has good simple wireing diagrams for almost everything ncluding the fuel computer.but your going to need a few extra componants if not already fitted.....
fuel flow meter
speed sensor
