Notes:*1 Also found at the fuse box. There are at least 5 RED / white wires at the fuse box, some will only pick up individual doors, meter them to find the one that will get all the doors, it will be the one that goes up to the instrument cluster, it is in a 12 pin plug on the back of the fusebox. For domelight supervision use one of the individual door triggers. *2 The lock wires are about 18 gauge. They will test only by operating the key in the passenger door lock cylinder, not the rocker switch on the door itself. *3 On vehicle with the factory alarm, can find these wires at the alarm module above the drivers kick panel.
