Almost been a year since I did this, but I believe you want to connect the eom aux switch and harness to a set of PIAAs, correct?

So you'll be cutting off the end(socket) of the piaa wire and then cutting off the huge end of the oem ware harness, and you want to connect them together.

The PIAA wires will have one wire(white) I believe that doesn't actually connect to anything, that will be tossed with the socket, the piaa instructions indicate pos and neg, but I believe the white was pos and the black neg.

So you'd end up with a white and black wire to connect to the aux harness, which is 6 wires.
I have this pic, I put together based one another member's pin order description (upon using it) I believe the pic is wrong (had to redo my wires, but didn't write them down), but the 2 grounds are correct, so don't crimp anything until after you'd made sure.

The switch should light orange (back light) when there's power at the switch, little box is green when it's "on", obviously the lights will work when it is on.


Far as powering the switch you have options, tapping the rear diff button"lights on" power wire.

Running a wire from the fuse box, either power on with key, full on, or lights on.

I did mine with "lights on" but not with bright's on like the Toyota lights, so I wouldn't turn them on without knowing, plus they will time off if left on.

You need a ground point for the switch, there is one behind the switch panel under the radio and another below the fuse box, see my installs for more info.

Here it is... this is from the oem wire harness to the PIAA switch

I wanted to use the PIAA wiring and replace the PIAA switch with the OEM aux light switch. There are 6 wires with the OEM, 3 with the PIAA. In the picture above... you attach the red/green & red/blue wires from the OEM wire harness to the white wire from the PIAA switch wires. The green/purplish wire form the OEM wire harness to the red PIAA switch wires. The black OEM wire harness wire to the black PIAA switch wires. This leaves 2 wires left from the OEM wire harness, grey and purple. The grey wire is tapped into the white/green wire coming out of the ATRAC wire harness. The purple wire is tapped into the green wire coming out of the ATRAC switch. By doing all this you are able to use the lights when ever you want to. As oppose to when Toyota thinks you should. P.S. I ran my wires for power into the fuse box and used the 10 amp Dome light fuse for the 510 and the 10 amp Horn fuse for the 520.
