tested the pins on each leg of the relay, the two from the door motors sit at postive, the two grounds are negative, the two pins suppose to be postive are postive. so the top rail is postve and the bottom rail is negative (as per diagram). But the ones going to the led is neither negative or postive when pulsed.

The two from the door motor wires should only go pos for 0.8 seconds on arming and disarming the alarm. Otherwise they sit on ground (earth) at rest.

Any way the whole concept is daft, the alarm's LED will tell you when the doors are locked.
