remote central locking install

[Jinster]

MY97 Australian delivered car. Has driver side and passenger side keyholes. Has central locking. No remote. No alarm.

I just installed an aftermarket alarm/remote/proximity entry unit. I will write up a DIY if there is enough interest but I believe most people from the US would have the remote feature as standard. Come to think of it, there is probably not much to write. Everything you need to know is below:

1. Everything can be hooked up under the passenger seat (RHD car) except the ACC ON signal, so remove the seat first (4 screws)

2. A Bentley manual or a wiring diagram from the factory manual is an absolute must, and contains all the necessary information to figure out which wires to splice into.

3. The door motors are negatively triggered

4. The door open trigger is labelled "door contact" on the wiring diagrams. I am unsure the difference between this and "door safe" - which also appear on the wiring diagram.

5. The door open signal is negatively triggered.

6. There is a separate trigger for "door contact" (door open) for each door, and there appears to be no combined signal. You might need an additional relay if you want your alarm unit to be triggered when either door is opened.

7. Unlock signal is labelled "unprime", and a single connection would unlock both doors.

8. A single lock signal would lock both doors.

9. The wire colours for a RHD car are: Red/Brown (thick) = 12V, Brown/Red (thin) = motor to open door, Brown/White = motor to close door, Brown/Green = (RHD) driver door status (closed), or LHD passenger door status; Turn signals = Black/White, Black/Green

10. Don't splice into the dash central locking switch (inside handle not secured), use the direct connections to the motors above

Thanks a lot! It was really helpful for me! The diagram of the car was so confusing with all those similar names! I had only a problem with the unprime cables... one of them didnt work and the other was good! Well thanks again it works great! :)
