Best bet is open the splice and go from there. It arrived without any damage, which is important to me being that I'm in the shipping industry. Really, this is well worth it. I took the gound wire off that is connected to the frame to the gas neck. If only the rear end is acting up and you just removed the bed recently remove any rubber and paint between the bed sheet metal and the frame. Plate lights work good all the time.

When harness connected, hot shows up at all bulb contacts, to frame. I will try to ground the bed to the frame and see what happens there. That splice should then be connected to frame. Second, they say to use velcro, which is a good way to mount.
If you were to then ground the hot side of brake bulb with a jumper, then the brown wire would try to light the park bulb in series with the brake bulb, and the result would be dim bulbs at best, possibly blown fuse park fuse. No moisture in the lens problem thus far either. It is in showroom condition and I really bummed to find out the pricing on other websites. There are a few issues though that may be considered. If I understood correctly, you get the correct result when harness unplugged.
If so you may be losing continuity back to the battery via the engine ground strap. Is this where I search for the splice?? I lifted the bed off the truck, replaced the fuel pump. Wiring can be confusing and frustrating for a lot of automotive enthusiasts. There are spots all around the housing where they missed and chrome shows up amazingly well against a black background! I was leery that it would be the right part. My tail lights are working but are very dim at times, turns work good until I push on the brakes, parking lights don't work, back up lights work until I push the brakes.
I left for a 4 hour trip with my tail light intact. When I arrived at my destination the lens was completely gone. There are several places where the ground wires leave the harness and are bolted to the frame. Thanks David Did you put rubber shims between the bed and frame. I will also check the parking light fuse again. A safer way to test would be to unplug the harness and jump just the brown wire from front to rear plug, leaving the other three unconnected and harmless.
Does that make sense to you? Yes When harness connected, hot shows up at all bulb contacts, to frame. By harness I was referring to the 4-wire that comes from front of truck. But I left those in place. It's something of a head fake, trying to use it will fail to have useable power. Now long story but I work for the state and was driving a state truck.

That would cause the combo switch and flashers to get a super load from short and may cause expensive replacements. This is all about black wires, not the 4 from the front. Follow the black wire from any brake or tail lamp to find the splice. I am very pleased with it.

It's got to be a ground problem.
The lights great though, just be prepared to touch it up when you get it! Very easy install, this is the most electrical I've done and I spent maybe a couple hours doing so. Rather than go through the delayed accident investigation just replaced it on my own nickle rather than go through the hassle. Most wires come with an easy to read diagram. If you like dressing up your vehicle with crazy little things like this, these little lights are a decent addition! Meaning that in each socket, I get power on each prong so there is no ground there to complete the circuit. It was very easy to search for the part I needed. You may wish to test that, just be sure that you don't activate the switches for brake or turn or hazards. I understand what you are saying.
First, they are a bit of an eye sore; just a big black box hanging at the bottom of the door. The problem is that this is clearly just the chrome version of this light sprayed black. Most products come with detailed instructions for easy and safe installation. Turning on park lights gives hot from brown on front harness to frame. Or run an independent ground strap from the bed to the frame.
