1989 Skyline R32 GTR, Keyless Entry

I installed a CrimeStopper RS4-G5 on my 1989 Skyline. The remote start works perfectly fine however I can’t get the keyless entry to work. There is a 3 wire plug that goes into the brain of the system for the door locks. Red/blue/green. I connected the red wire to constant 12v, blue wire directly to the blue wire of the actuator and the Green wire directly to the green wire of the actuator. The car has a central locking system OEM but not a true power door lock system. Also when I lock the doors from the remote the brain clicks and the red led flashes normal but doesn’t actually lock the door. When I unlock it clicks again and the led stops flashing. Any help would be greatly appreciated.

It is a regular key. Just stating that since the forum requires it and I like to follow the rules 😜
