Ok Im building up my Mk3 Fiesta with a 2.0 Zetec, It should only be a week or two from being ready to go but I'm getting a bit worried about if its going to work or not. Ive tried searching but I can't seem to find a conclusive answer.

The car has an RS1800 loom from front to back, and I have a DESK ecu from a Mondeo. Will this setup work or will i have issues with the ECU being internal EDIS and the loom having a connection for an external EDIS module?
