I have a non-locking drivers side floor harness, runs under the drivers seat, to console, then 1/2 up the DS door pillar, through the rear DS door sill to the back of the truck. I also have the harness that connects to the floor harness on the DS to the PS side. And the one that connects the sill harness to the ABS sensors.
If this is a Lexus it will have the additional wires for the locker reguardless of whether you have the locker or not. If you don't have a locker you don't need them but these harnesses will be different but will have all the connections you need. They are to install.
