Central locking wiring

[sandman]

Hi everyone. I have a 59 Berlingo van (625 X) model. Pretty basic model but it's superb. I'm hoping to fit a keyless entry on it as it only has key operated central locking. I have the kit from "rightclick" and it's pretty simple to understand. All i need to know is- does someone on here have any idea what colour wires do the following job: 1,Front door unlock 2,Front/All doors lock 3,Rear door unlock? I hope this is easy to understand. There doesn't appear to be a workshop manual available for the new shape Berlingos. Cheers guys!!
