I picked up this led light off ebay, and want to mount it in my truck cap. A recent camping trip shed light that I need some light. As you can see, its a 2 wire setup with an off switch. I have no idea what to tap into. Something in the taillights? Im hoping for constant power, not switched, and pray I remember to turn it off. Im an electrical weenie, so be prepared to answer questions. Pics would be great! Thanks in advance.20190115_163113.jpeg20190115_163117.jpeg20190115_163123.jpeg

Headbumper....
What truck is this going in?
Any trd packages?
Tow packages?

Im no guru but the above info might help someone else.

The easiest answer i can give would be to run the wiring to the battery with an inline fuse.
 
I don't sparky much, but I agree with Jangley. I think your simplest and probably best way would be to run a dedicated, constant powered, sufficient-plus-a-little gauge wire with an inline fuse back there. Wouldn't be interfering with anything else if the wire ever happens to short out and pops the fuse.

This is what I would do. Easiest solution and less risk of compromise to any other system.

You would have to check. My GMC had a constant hot wire. Not positive, but I would assume for electric brakes. Haven't had a chance to check my Toyota.

Could be a big help, thats what i was hoping for and why i asked if op had tow or trd packages. Good to see this could be a possibility.
 
 
This may be more wiring than you want to run, but if you could route a small maybe 16 gauge wire from your cap to the engine bay you could get an “add a fuse” and the DRL fuse has constant power in it. All you have to do is pull the fuse and place the add a fuse in its place. The add a fuse has 2 slots. One for the fuse you took out and one for the line you’re running to. No cutting in your factory wiring and it’s fused. If your light already has a switch, there’s no need for anything else. Just route the wire neatly under the cab tucked and tied away and you could easily find a bolt closer to where your light is going to be that would serve as ground so you wouldn’t need to run a long ground wire. Hope that helps
