Adding LED reverse lights, where to get power from?

[greenoliver1]

I want to add 2 small LED lights to my backrack on my 2015 Silverado LT. Got the lights, harness with relay and switch. I’ve installed them on late 90’s Chevys that had a AUX power supply at fuse box under hood. Do these style trucks have an AUX power hookup? Or do I need to run my power wire straight to the battery? Thanks for the help!

It is easy to tap into the power at the 7 pin trailer connector at the rear bumper.  I used the that power for my led bed lights.  The only issue with this power source that it is constant on.

Sounds like you found the 12V wire, as opposed to the reverse wire.

Correct, Chris.

You might have already found your answer but I tapped into the reverse wire in the trailer pin harness. They only come on while in reverse. Had it for a few years now with no issues.

I'm looking at hooking up Aux also, I want to control them from the Bed Lights, isn't there Block somewhere under the bed where I can tap in ?. I want to use the lights when needed, don't want them coming on when I lock the truck at night at the campground and disturbing fellow campers.

There could be a way to tie them into the actual bed light switch in the center console, @pgamboa might be able to help. Works best to shoot him an email at harnessdr.com. 

 

I wired in aux reverse lights but did not want them to always be on when the truck is in reverse, so I improvised and put a switch from otrattw in, and tapped into a constant 12v signal in the drivers side fuse panel via an add-a-fuse. Super simple install, below is the write up I made. Not sure if this is what you are going for just throwing out some options!

I installed the Rigid flush mounts also.....but I ran #14AWG wire directly back to the battery, through a relay.    I didn't want to tap any existing 'reverse light' wiring at the rear bumper.  Didn't trust it to be big enough.

Correct, Chris.

I was working on a couple of our trailers here at work over the last few months.  One of our trailers was ALL F'D UP at the plug, only the RT turn and ground were correct.  Told them that like 2 years ago.  I had done some of my own troubleshooting, and told them which wires they had where.  "They fixed it," and still had a few on the wrong pins.    Management will NOT let me fix it, "our AGE mechanics have to fix it."  This particular trailer is a "lift trailer," AKA "low boy," and the battery wire is on the tail lights pin and the tail lights wire is on the 12V pin.........STILL!!!  Day Shift turned in the trailer for maintenance, "dead battery," today.  Last time, all AGE did was replace the battery.
