Thanks for the response. I have the 21 circuit harness. Electrical wiring is not my strong suit but I will look at how they call out the GM way in the manual. I am hoping to use the toyota switches if at all possible but it may not be an option. Any help you might provide would be greatly appreciated.I don't have a callout for the plugs, but the way I reintegrated my painless into the Toyota was the GM way, both the blinkers and the hazards get their own flasher. It's easier to integrate that way, instead of running flasher power first through the hazard switch, then to the blinkers.
How many circuits is your painless? I'll dig out my notes if we have the same painless harness. I have the 21 circuit harness.
