Looking for open fuse in engine fuse block

Hi all. Long story short, I wired up my CB and dashcam to an open fuse in the drivers-side fuse block, and fried the whole thing. (Really!) Cost me a good bit to get it replaced.

 

The dealer said I was drawing too much to tap in to there, and I should go to the engine fuse block instead. I've tested all the open ones on my truck (an LT) and didn't find anything with power with the key on.

 

Does anyone know if any of the full ones are safe to pull? Or how are other doing it? Thanks in advance!

A CB and dashcam shouldn't pull more than 10 amps, i've used fuses on both passenger and drivers side fuse panels for plenty of accessories with no problems.

 

Do you want it only when the truck is on? or always powered no matter what?

For my dashcam I require both, one for driving recording and one for parking recording. So the dashcam knows when the vehicle is on vs. off.

Hi @AaaaaaaayushI've always wired my CBs to the interior accessory panel too, however, behind the passenger fuse block there's a circuit board - somehow it got fried and I had to replace the whole thing. I have the old one that they replaced I can take pictures if you're interested. I've been doing radios & CBs for 20 years, never had an issue, but I'm not going to risk it again :)

 

I bought a relay that I'm going to wire in to the passenger fuse block to activate it, and then go right to the battery for the juice. We'll see how it goes!

      I’m having every problem imaginable, PLEASE HELP
      By qoconnell
      This is my first post so sorry if I’m all over the place. I’ve had my 2014 Sierra slt for about two years now. I got it with 116k miles and I’m at about 174k right now. Since the day I’ve bought the truck it’s been nothing but issues. You name it, it’s happened. Four separate water leaks (sunroof, gps antenna, third brake light, and cab vents), 2 transfer case control modules, problems with the power steering going out, brakes going out at low speeds. A couple of months ago my transmission went out and it also needed various other repairs totaling over $20k. Now my park assist sensors don’t work, my rear doors don’t open from the inside and also don’t lock from the outside, reverse lights and camera don’t work, and it constantly dings at me to service my trailer brake system (seriously, it chimes at me about every two seconds as I’m going down the road, telling me to service the trailer brakes). I’ve gone through and checked every ground I can find and nothing helps. Today I went through every single fuse and relay in the truck. I found a couple of blown fuses and replaced as needed, but still no change. I’m at a loss for what to do at this point as I’m stuck with the truck after all the money I’ve sunk into it. Does anybody maybe have any solutions to any of these problems? I’m desperate for answers, anything helps.

      Jump seat swapped for a full center console.
      By Addichevy
      Got my full console from Ebay used in like new condition. I did alot of research to figure out how to wire it so all the functions would work. I.e. wireless phone charger and  usb/ cigarette liter ports for the rear passenger.
      I have a currently have a 22 2.7l Custom that doesn't have the required connection under the front passenger seat. After hours of looking at schematics and testing wires, I managed to hard wire my center console to the fuse box on the passenger side.
       
      Wire on the CC harness to Fuse box
      Both Red/white to F5 (Battery positive)
      Violet to F20 (Accessory on)
      Violet/yellow to F23 (Accessory on)
      BOTH Black to Ground below the Fuse box.
       
       
      The only section I wasn't able to get working yet is the USB in the middle of the console (the one with the map SD card). This one I believe needs to be connected to the radio that has the built in navigation. (once I get one I'll update this post.

      Eletrical problems after body work
      By Jeremy Hasenauer

      Just got some body work done to my truck last week. They replaced the hood and roof due to heavy hail damage. When I got my truck back I noticed a few things not working.
      Driver side door no longer turns off radio and dash lights with ignition off and door open but passenger door turns everything off. Dome light does not turn on, 3rd break light does not function anymore. Rearview mirror air bag indicator for passenger seat doesn't light up anymore.
      I've check basics like fuses pulled the headliner down to see if the wire had been cut. I haven't had time to dig any deeper but will plan to check to see if I have power at the connectors tonight. I really don't want rake it back and throw a fuss if it's something I can fix myself for cheap.

      Okay so does anyone have an idea how to fix my fuse box? The problem is I'm missing the internal connectors to plug the fuses into. Its my two power fuses, someone must've ripped them out to hard.
