Hi all, im just after a bit of technical advice if i may?
Th'engine is knackered on my missus 1994 gold 1.4 3 door and we have bought a vento fronted '97 GTI 5 door AGG as a donor

. The GTI is in perfect running order with a genuine 100,143 miles and full history and i am doing the conversion this weekend.
The issues i have are as follows:
It has a sigma alarm connected to c/l on all doors, so what would i have to do to remove the electrics that go to the rear windows/locks without affecting the other electronics?
Also, im doing a full conversion so i am swapping all the abs unit and re-making all the brake pipes too so that everything is done properly. Is this going to involve full pedalbox swapping and what do i need to look out for?
Im a fully qualified mechanic but my electrics knowledge isnt the best!
Any help on these would be greatly appreciated as i want to make sure im doing it all right!!
I will be taking pictures/notes whilst doing the build so i will provide a full illustrated guide once its finished and running, in case anyone does want to try a similar thing in the future. The main issue i think is transforming from a 3 door to a 5 door.
Thanks guys (and gals), Mike
