Hello boys and girls. First I like to say that my English is not the best in the world.

I got a problem, I think one of you can help my whit. My project is to build a Fiesta Rst engine in my Escort Xr3i EFI from 1990. I have read that I can use my original wiring, but need to change some pins in the plug were the ECU is connected. I got a OFAB ECU, map sensor and engine wiring from a Fiesta RST. What are my choices? Thanks alot!

Kind regards Ronni Knudsen - Denmark
