Evening boys and girls I'll start by introducing myself as this is my first post and most definitely won't be the last haha. Am Steven from a bloody freezing Aberdeen. Iv been a massive fan of ford's and always wanted a project but having kids other things take priority unfortunately.

I now have a mk3 fiesta 1.1 and have also bought a 2l mk2 mondeo and will be doing the ever popular conversion. Unfortunately it's a PATS mondeo so not the easiest of starts. My original plan was to just buy a 1.6 wiring loom and deep/desk/dewy ecu but since I have the entire mondeo could I use it's loom and ecu and just transfer the PATS into my fiesta? So basically having PATS in my fiesta and allowing me to run the engine using it's original loom and ecu. I can't see why it wouldn't work as I will have everything needed to do this but would this be too complicated and id just be better of getting a 1.6 wiring loom and 2l non pats ecu? If it will be simple enough what would I need to take of the mondeo to make it work?
I've read many guides about PATS but can't seem to find anything about installing in a car.

Any advice would be muchly appreciated and sorry my first post had to be about PATS

Thanks steven
