OK have had some S--T heads trying to break into my toolboxes so bought a Viper 5706 alarm, it does 2 way paging, remote start etc but was just going to install it and use the door switches, shock sensor, run the trunk wire to the toolboxes and use a reed switch. My question is about the central locking my Hilux (2006) has the central locking activated via buttons on the key, the alarm has the wires (-) to lock and unlock, where do I splice these into ?
