Central locking

[AlanN]

Does anyone know how a 5 wire motorised door actuater works. I have searched for diagrams on the net, but I cant find anything that tells me what wire does what.
I have a alarm which will operate the door locks! On 2 wires from it, I get a pulse down one when it opens and down the other when it closes.
THen have a 5 wire door motor, but I cant sus out what wires do what, I understand that 2 are for the slave locks
Can anyone help me out here

What make are they?

Its got Spal on the side...

I have also got a 2 wire one, which I could wire up using two relays, but I wanted keep it as a slave for the rear door

I found this diagram on 12volt.com, I may give this a go and see if it works... Anyone got a better idea

Both motor legs rest at ground at the relays. To lock or unlock the vehicle, polarity is changed on one motor leg.
Or a £20 relay

wire them all as slaves and you won't need the relay - depends on the alarm of course

The problem is there isnt a positive supply to activate the motor, so the relays will switch + & - either way when the alarm supplies neg volts to one or the other relay. Hell it works, the central locking works great now from remote.
Just got to sort out what wire to cut in the column for the imobiliser wires now, to shut off the ignition.
