Fixed several issues. High beams, rear running lights, and trailer lights.
2005 GMC Sierra 4dr crew cab w/ 5 3/4 ft bed 2wd. For a while I've been trying everything to fix my father's truck. Rear DRL didn't ever come on but brakes worked, hazards worked, and turn signals worked. Also the high beams would never come on if you tried everything would just go dark. Even found out the trailer light connection wasn't getting any power. Changed bulbs, fuses, relays and nothing ever worked. Finally tried this and it FIXED EVERYTHING! was so happy. Part is easy to replace and feels and looks like the OEM part. 10/10 Quality. 10/10 Fit. 10/10 Connection Seal. Highly recommend 👌

Worked perfect on 2008 Silverado 2500HD
Worked perfect and exact replacement on my 2008 Silverado 2500HD. My taillights were doing some crazy things like reverse lights on with parking lights and flashing on left side with right blinker on. This fixed it. Easy to install, it’s was located on the crossmember to the left of my spare tire. It was easier to unbolt it with the one 13mm bolt than try to pry it out of the bracket on the truck. Cheap and easy fix.

Solved Turn Signal Issue
This part is crucial for the proper operation of your turn signals, as well as the back up lights. The wire block connects all the rear tail light circuits. This part solved the rapid turn signal issue. Save money and fix it yourself. Thanks Amazon.

Have a 2012 GMC Sierra had my lights go all crazy, turn drivers side turn light on and all lights would flash including my ID lights. Thought it was my trailer plug. Unplugged it and it work a week later the same problem happened again. Bought this junction box plugged in my trailer plug and VOLA! Everything works fine again. Thanks so much.
