I recently did a bed swap on a 06' Chevy 2500. 2011 Chevy 2500 bed, with taillights. I'm currently having a hard time wiring the taillights. I have them turning on, running lights, brake lights and signal lights. But when I hit the brakes, the front running lights come on, and when I use the blinkers, the 3rd brake light also flashes. When I hit the brakes, while the blinker is on it also stops the blinking. Any suggestions?
