Can anyone help me with this one ?

The remote central locking is very intermittent on my Legend, although it works everytime when I use the key. I suspect the C/L wires from the remote control alarm box in the passenger footwell might have a break.

Trouble is I don't know which wires are for the central locking circuit, and I don't want to mess with it and find I've messed up the alarm or immobiliser.

Does anyone know what colour wires I should be looking for ?

Thanks
