Today I spent wiring up a 7-pin trailer connector. I have the M1 smutty build bumper for my 2007 FJ. Got the 7-pin right in the center of my bumper over the hitch. Someone said it could not been done due to the bumper frame was in the way, but if you run the cables over the top of the frame it works. Could not show you sequential turn signals due to can't up load a video.
