Hi to everyone, i am having some troubles with the installation of a keyless entry system kit on a 1998 seat Ibiza 6k 1.9tdi (i cannot post the link however you can find the kit on ebay). I have pneumatic door lock, and on the pump i have three wires: one goes negative, one +12volts when car locked and 0 volt when unlocked, the last one +12 when unlocked and 0 when locked. I found out that one wire is coming from driver door, the other from the passenger door. According to the manual of the kit the pump has one positive wire, one negative wire and then a "main" wire, which i think it's the signal wire. However on the car the circuit is different, indeed the kit does not work correctly. Is there anyone who successfully wired a similar kit, or can provide me a decent guide for installation? Thanks in advance.
