The door lock outputs on this system are surprising complicated. There are 3 wires for lock and 3 wires for unlock. On the car I have allready found one wire (-) pulse to lock and one wire (-) pulse to unlock. I through testing and a relay I have beenable to make one of the wires on the unit give a negative pulse when the button is pressed, the problem is that the same output wire gives the same pulse every time the button is pressed (it goes back and forth)

Anyway Is there something I could do to make this single output lock and unlock the doors?

Or does anyone know how to get this fai8100 door locks working with this setup.

It is a porsche 911 Carerra 4 1989

(also If anyone has a tach wire for this car that would be great, The12volt diagram said green but there is no green at the coil.)

There are 3 wires for lock
3 Wires for Unlock
There is only one transmitter button, that either locks/unlocks

Lock

Black
Green
Pink

When black is grounded green is constant (-) unless button is pressed then it loses ground for one second

When pink is given + then green wilil reciever + when the button is pressed.

Unlock

White
Blue
Orange

Have gotten no result out of these wires.
