The Theory
When I came to fit C/L to my car, I was originally going to use the Universal Kit as whole. But upon removing the door card, I realised it would be much more difficult to fit the motors to this MK2 than it was when I did it in my MK1. This was due to the fact that there was no where to attach the motors pushrod to the existing door lock mechanism without cutting away at some of the protection around the door pin rod. Rather than compromise the security of it, I decided to come up with an alternative idea.
I thought about using the door locks from a MK2 with C/L. After looking at a wiring diagram for the C/L of a MK2, it was apparent that the systems worked in almost identical ways. Infact the only difference being that the Fiat locks had a third trigger that would not be required in this system (hence why the Fiat locks have 6 pins and the Universal motors only 5 wires.) So in theory going by the diagrams, if I got the wiring right and just leave the third trigger disconnected, it would be fully compatable with the Universal C/L module.
