I've had issues with truck electrics on my 04 Silverado and use it to haul a 3 horse Sundowner gooseneck trailer. This part came to my attention via an email from 1A Auto. The information in the email seemed to describe some of the issues I was having with my truck. And of course, there was a YouTube video from 1A Auto that showed how simple this repair is to perform. Ordered the part, usual speedy delivery, problem solved!
Great Price. Gsst Shipping

Replaced the factory junction block flawlessly. Only issues I ran into had nothing to do with this part. My driver side tail light/brake like stopped working and new bulbs didn't fix it. Best price on the internet for this piece and it's actually quite a simple job thanks to their tutorial videos.

The part was spot on. The easier way to change is just slightly flex the metal compression tabs and remove one screw. It slides out nicely and lets you clean the frame behind it. Reverse the process to reinstall, put the plugs in their respective spots and your done. Works great.

I had a 2011 Chevy Silverado 3500HD that had issues with the tail lights. When the running lights were on all tail lamp lights were illuminated but dim. When I activated my brakes, the left tail lamps would all go out and the right would illuminate all 3 lights including the reverse light. I cleaned the connections and it worked for a little while then the same problem happened. I replaced this part and now everything works perfect! Easy to install and 1AAuto's installation video was spot on. Much better than others on the internet. Thanks!
Good product. Exactly what I needed.

Quality a tad shy of OE. Fit, which it should as a "given"! Functioned as it should. Now the test of time needs to pass. The original was still functional and was replaced due to minor cracks that would lead to random issues.

This is possible as the power to the turn signals for both truck and trailer are combined.

Would this have anything to do with my rear parking sensors? They dont work and Ive tried everything except this? Thanks

This is the junction block for the lights, so they would not have anything to do with rear parking sensors.

Can I hook up trailer lights w a plug to this box?
August 16, 2021
Terry H
10
Yes, the box has all the connections for the rear light connections, including the trailer wiring harness. My truck already had a trailer hitch and electrical connection for the trailer installed at the factory, so it was a simple matter of just plugging in the existing trailer wiring harness into the new junction box.

Will this junction box fix issues with the third brake light not working?
January 9, 2022
John D
10
More than likely they have an led style third brake light and the whole light assembly must be replaced its a very common issue with them going out however if they unplug the wire connectors from the junction box and its severely corroded I would start there a junction box is by far cheeper than the led third brake light assembly

This junction box is for the tail lights only, not the 3rd brake light.

No it will not. This junction box is mounted in the rear of the truck, above the axel and has nothing to do with the third brake light. Good luck.
