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.

What wires do you need? I'm doing installs on these all day at the Toyota dealer; I have a few shortcuts.
