im trying to fit a laserline remote central locking unit to my 94 rs2000 4x4 but need some help please

Diagram 1 is pretty self explanatory I know where these go



Diagram 2 is where I'm stuck!



Firstly, does the alarm unit refer to the c/l unit or the remote unit?

Next, do green-black & yellow-black require a separate 12v feed (tho a 5a fuse) altho the unit already has a 12v feed (red on dia.1) or does this come from the c/l unit?

On the c/l the yellow is earth when open live when closed
White is live when open and earth when closed
So where do these connect to either grey-black & or brown-black?

Lastly the blue-black & red-black are ?
