I finally got my pop-up in shape and was ready to wire the harness. I very carefully followed the wiring diagram (I have the factory installed towing package, so the truck has the harness socket). But, something is screwy. As long as the truck lights are OFF, the trailer turn signals and brake lights seem to work. But if I turn the lights on, the brake lights don't seem to work, and the turn signals are acting strange. It's almost like there is not enough power, because it seems that if the lights are on, and I turn on the left signal, the right tail light will dim as the left signal flashes. Seems like I recall having to get a heavy duty flasher back in the day, but that was because the normal flasher would flash too fast when the trailer was hooked up. Am I missing something here? I know a little bit about wiring, but something isn't right. Jaminn aka Don Williams
