Central Locking Wire Colours


Supra ST Myster

Recommended Posts

anyone know the wire colours to connect my new alarm system to for the central locking to work, apparently there is a connector neart the fuse box drivers side that may have the ones i need to tap into?

 

When I removed my doors for a re-spray I had to cut two wires. One was orange, the other a pinky/purple colour. Upon putting the doors back on, the central locking wouldn't work without these wires being re-connected. From that, I deduce they had something to do with it. Maybe not the same for all cars though.

Bare in mind I've got a facelift car and I'm not sure if all the Supra's have the same wiring.

 

I checked them all first with my multimeter.

 

The following were located in the fuse box in the drivers footwell

 

 

The ones for the central locking on my car were .

 

The blue connector at the bottom right.

 

red/white wire goes to 0 volts to lock the car

 

red/green wire goes to 0 volts to unlock the car

 

 

 

Current sensing on my car.

 

Blue connector at very top left

 

The green wire is normally at 12 volts and goes to 0 volts when the door is opened.

 

 

 

Indicators on my car were.
