So I’m trying to wire some ledlights to light up my bed but the dummy plug under the truck has no power. Does anyone know what fuse might control that or does any know what might cause no power?

Maybe try turning on the switch for the cargo lamp and see if there is any power to the plug with it on.

In the factory set up, that toggle switch controls both the cargo lamp in the 3rd brake light housing on the roof and the two LED's under the bed rails.

That’s actually what has me worried because the third brake light bed lights work. With that switch on there is no power. When I first tested it, it did work but once I put the plug back on to test lights now no power. I was thinking fuse, maybe I tapped the power and ground by accident but I can’t find a blown fuse any where

Not calling you wrong but are you trying the correct dummy plug ? I had the same problem and it turned out I was trying the wrong plug.The correct one that works for me is the one on the complete left side when facing the truck from the back. Hope this helps you also if needed the correct power lead is GM part # 23327843 on my receipt it is referred to as a F-HARNESS ( also called a tailgate wiring harness ????? ).

I hope this may help you.

Yes. That’s the one I am using. The lights worked at first but I was adjusting the wires and I might have tapped power and ground together. They do not turn on now. My third brake light bed light still works but the plug has no power now and I can not find a burned fuse any where

      Well that book won't sell many copies. Taking ones right foot off the loud pedal never gets applause. Funny really, It isn't that people don't know what to do...they just don't want to do it. But they will complain about it. About bad craftsmanship, about the cost of fuel, about the cost of part and repairs and mainly they complain that the solution while still possible isn't one they are willing to do.    I observe this daily. 'Gas cost to much!", they wail, while they mat it passing at 80+ mpg and scoot down the road like gas cost a dime a gallon. Then complain about the few that will lift and save both fuel and iron like they are owed and own the road.    Good thing they haven't an ounce of influence on my equipment. The rest I just laugh at. Stupid is as stupid does, right Forest?

      Today I filled up with 4.899 gallons of fuel at a cost of $4.899 a gallon. $24 bucks. 290 miles. 59.2 mpg. After my 4% COSTCO discount just under eight cents a mile.

      14-18 Sierra 1500 Heated Steering Wheel Help

      By SwitchBladeSierra · Posted

      Howdy folks,   Recently I pulled a heated steering wheel and clock spring out of a 2015 Sierra All Terrain (part numbers coming soon - will have to disassemble), and just installed it on my 2016 Sierra WT (as base model as it gets).   On install, I noticed that I’m missing the connector often tucked behind the dash for the heating element.     No problem… or so I thought.   I used an “Add-A-Fuse” at my heated steering wheel fuse location, which has voltage, but no wires. I ran it to the positive of the heated steering wheel (Violet/White), and took black to ground.   Hooked up the battery, turned the truck on - no heated steering wheel. No button backlights. Was pleased to see that my cruise control was working though.   Read a post suggesting reversing polarity, so I gave it a shot. Violet and White to ground, Black to power.    Aha! Heat! But I seemingly can’t turn it off AND still no backlights on any of the buttons.    Checked all fuses, everything is still in good order. I’m stumped.   Does anyone have any insight? If so, please share!

      Brake Pad Warning Message

      By TrueBlue · Posted

      I'm about 1800 miles into my last oil change, and yesterday a message appeared saying oil life was at 77%. Not sure why it popped up but I think all of these electronics could be susceptible to solar flares or somesuch. I change my oil right at 3K each time, and that was the first time in 10870 miles that message came up. Strange thing is that it showed on the screen at all since I don't drive with that sort of info displayed on the DIC.
