Magicar Fai 8100 Door Locks

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

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.

Have gotten no result out of these wires.
