I have a alarm and there is a spare orange wire, Iv been told this connects to the central locking, this would be really cool. Anyone know if this is correct?
it's not really as simple as that you need to put +12v on one wire to lock and a differnt one to unlock. Are you sure there's just one orange wire? Most alarm systems have a relayed output and usually 6 wires to fit all types of central locking.
