Tailgate LED Bar


Recommended Posts

If we’re talking about the Putco harness, then you don’t have to worry about the 7 pin connector, or tapping into anything else other than where it’s supposed to go. And that is on each side of the truck, where the connector for the tail lights is. Then the harness has a dedicated connector for the backup lights that goes to the wire in the light bar. Simple, really

Maybe you just have the light bar itself, installed backwards. It’s pretty common. The connections for the bar are usually on the left, driver’s side of the truck as you look from the rear.That doesn’t exclude that you can’t swap the harness around. Good luck.

Hello everyone! I am on my 3rd Sierra and on my third Opt7 sequential tailgate bar. My newest sierra is a 2021 1500 AT4. I am reading the putco harness will plug right in with my Opt7 tailgate bar. Is this true even on the AT4 model? My last 2 I was able to hook into the trailer hook up and now it looks like that is no longer possible. I also have the trailer package. Any info would be greatly appreciated. Thank you!

Putco Blade tailgate light bar and the Putco harness works great without using the trailer plug. Perhaps you can modify the Opt7 wires to match Putco harness if it's not a direct fit.
