I'm trying to install led bed lights on my 2006 ram 1500 so I can see up under my tonneau cover at night but I don't know what wires to tap into for a constant power.

If you could tell me what color wire on either the tail light harness or the 4 pin trailer harness I would really appreciate it.

Should be the BROWN wire if you want to hook it to the 4 pin trailer harness to come on when you turn on your lights..... just googled "4 pin trailer wiring diagram".

I don't want them on when I turn on my lights. I plan to install a rocker switch inline so I can turn the bed lights on and off without having to enter my truck or have my keys with me. I need a wire that's constantly drawing power, not one that only gets power once another switch is turned on.

I don't even want to go through the hassle of that wiring job. Besides, if I do it that way, I have to have my keys on me and flip the switch inside the cab. I want to hook it up so I can just flip a switch I install in the top corner of the bed.

Is this the 06 dodge ram wiring setup? If so, it looks like (if I'm correct, which I might not be, wiring is my weakness) it looks like I want to tap into the red wire, if I want to be able to turn the led lights on and off without having to do anything else.

Is this correct? The red wire in the 4 pin trailer harness is a constant 12v power line?

There is no powerwire in a 4 pin. That diagram shows a 7 pin system. If you have the tow package, you may have a power wire there at the 7 blade.

I have a 12v outlet in my toolbox and a flashlight charger. I ran a 10ga fused lines from battery to toolbox for constant power. It is not hard to run a wire back to bed, from the battery.

I guess I'll just run one under the truck up to the front and into the engine bay and zip tie it up nice and hidden. I'll throw a fuse on it too close to the battery. Don't really have any other choice it seems.


I did see a YouTube video of a guy with a early 3g (04/05 style) and he cut into a constant power wire under his bed. He wasn't clear on what wire it was he just kinda said I cut into this wire here and never said the color and the video was too dark to see.

Someone has to have spliced into a wire back there for bed lights. I know every single person with bed lights did not wire them to their cargo light switch or run to the battery. I know many have wired into a constant, but it seems nobody is around to chime in and help.

BTW I have a 4 pin trailer harness. My truck did come with the tow package. Where would I find those wires? Is that the plug up under the little black "door" on the rear bumper by the plate?

Yes, that is the 7 blade plug. Take a meter and test each pin with lights off. See if any are constant 12v.
