Hi Christopher, I have the wiring diagrams for the c/locking but it depends on what month your car was made?? before or after September 2000 basically they are the same but for reasons best known only to Mr Ford he changed wire colours around?? the basic c/locking as I suspect your model has there is no module controlling the system there are 4 wires that run from door to door orange/black or orange/blue 12v, black earth, then pre september white/violet or green lock, yellow/black or blue unlock, post september supply and earth the same but yellow/blue or black lock, white/violet or green unlock. Your remote locking device will need to connect into both of the lock and unlock lines.
If you want the diagrams contact me and I will mail them.
