These actuators have 5 wires, and others have 2, so I assume the 5 wire thing is the detecting the locks thing.
Autoloc actually sent me a 4 door kit when I ordered a 2 door kit. So I payed less and got 2 free actuators and a shit load of extra wire and stuff. Good deal. So if I ever find something I can use those actuators for that would be great.
