I'm trying to install remote central locking into my 2001 "Monerto". They are called Challengers here in Australia. It has the standard key central locking but I bought the universal remote locking kit off the ebay so I dont have to use the bloody key in the door. As per usual the "chinglish" instructions are unhelpful.

It's driving me crazy as I cannot work out the wiring. I can get it to either lock or unlock but not both. So I am obviously not wiring it up correctly. Hopefully someone can tell me which wires go where.

The plug on the unit in the car has 6 wires:
Black/Red
Blue/Black
Black/Red

Blue
Blue/Black
Blue/Red

The wiring on the universal locking kit is:
Orange = Foot brake
Yellow = Accessories
Blue = Door switch negative (activates interior light)
White = Indicators (Blinkers)
Green = High Coil Relay
Brown = Horn/Siren
Red = Postive power (constant)
Black = Earth
White = Unlock
Brown = Lock

I cannot work out which wires the white unlock & the brown lock attach to on the unit in the car. I have attached a test light to the wires and determined that the blue/black is lock & the blue/red is unlock but when I attached the corresponding white & brown wires from the universal unit it will not function. Then I attach the white to the red/black and connect the brown to the blue/black and it will unlock but not lock.

Anyone wired one of these up before? Not matter what I try I can only get it to lock or unlock but not both. PLEASE HELP!
