Purchased a trailer wiring kit off etrailer that uses the exact same male/female connectors to the combination lights for a different Toyota vehicle. I did have to re-pin the connectors so they properly match up with the HZJ77 connector pin locations for brake, tail, and turn signals. I tested everything after re-pinning the connectors and hooked it up....and it worked perfectly.
What is nice about this kit is that I can now tap into the wires of of the wiring kit rather than butchering and splicing the factory OEM harness for the bumper lights, The 4-pin trailer connector can also be easily adapted to 7-pin trailer connector as well but that is a project for another day.
