Problem Solver for Truck and Trailer Lighting

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.

Yes if the contacts are corroded. I would check the receptive on the trick side first and work your way forward. I just spent hours t-shooting mine to find the contacts in the 7 pin recepticle we're corroded

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.
January 10, 2022
Tim K
10
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.

I have a 2002 Suburban that has an issue a the plug harness not having ( or sending) the right brake light signal or turn signal.  Does this part feed that signal?  All other lights and signals are being sent through the plug at the rear of the truck
