Question about 2001 Chevrolet Silverado 3500

1 Answer

I bought a new 2001 one ton chassis and had a flat bed put on it. They installed a 4 prong female plug(the round kind) for trailer lights. The other day I tried some of those temporary magnetic lights on an old trailer. Well they fell off and broke. Now my brake lights don't work on my truck. Any suggestions?

I would look under the rear of the truck to see if the brake wiring got pulled off. When hitch plugs are installed they have to tap into your brake wires. If they fell off they might have pulled all of the wiring loose so nothing will work.

I have a standard 4 flat trailer plug on my truck but my trailer plug is also a 4 flat plug but has two brown wires going to one prong. how do i hook them together to make all my lights on trailer work

The 4-wire flat plugs usually have a white (ground), green (right brake/turn) yellow (left brake/turn) and brown (taillights - left and right). If your brake and turn lights work but the taillights don't, check the plugs (trailer and truck sides) for corrosion, and chek both the trailer and truck wiring harnesses for chafed insulation and bare conductors on the brown wires. Likewiae if the taillights work and the brake/turn lights don't, perform the same checks on those wires. And last but not least, be sure that the white wires (truck and trailer) are grounded well to the truck body and trailer frame.

Depending on what connector you are using, here is a link to the wiring diagrams:

You may have to use an OHM meter to test the leads at the tow vehicle side to verify correct placement. Good ground is essential too.

Trailer Light Kit (2007 Jeep Wrangler)

I would not hesitate to buy it from auto zone. The 7 prong will have only 3-4 usable prongs, the others will be empty. The flat 4 prong is the same, just flat and only have the usable prongs. I work for BOSCH and this is a big example how bad people get ripped off. We make an aftermarket oxygen sensor for almost any car. It's produced for about $7. Sold to parts store for $12, and then sold to you for $60+ , It is produced the same way with the same components. But we also make the OEM for $7, sold to dealerships for $17 and cost you $100+. Dealerships are a rip off, but people hesitate to buy aftermarket parts when they are usually 100% made the same. It's all about money in the long haul for these dealerships. So buy the aftermarket 4 prong kit.
