Is there an "easy" way to wire up a switch to the reverse lights?

If possibly, I would like to wire up a switch that would turn on the reverse lights without having to put the truck into reverse. Could I just add power to the back up fuse?

The idea is that I could use the reverse lights to light up the area behind the truck to help set up camp or what not. Currently I've been leaving the truck in reverse when I wanted to use the lights but then I would have to leave the keys in the ignition. Would prefer to be able to remove the keys, flip a switch, and have the white reverse lights turn on.

Just a suggestion, you can get “rock lights” that are really cheap on amazon and will light up the area better than your reverse lights- and much easier to put on a switch. Good luck!

I've thought about it and definitely not a bad idea but just trying to keep things simple. My last rig had WAY too many mods, trying to keep this rig to the point.

According to the shop manual, it is a really simple circuit:

the two bulbs get power from the ignition switch and are turned on / off by the: AT park / neutral switch, or MT backup light switch

So, if you were to supply your own +12V to the wire going to the reverse lamps that should work with no downsides:

Identify the color of the wire at the back up light bulbs (one is power, the other goes directly to chassis ground), then under the scuff plate, or front kick panel (not sure if it will be on the RH or the LH side, may have to check them both to find it), find that same wire (confirm it with an ohm meter to be sure), and splice in your dedicated power supply and switch.

Do NOT forget to turn it off before driving. Use a switch with an indicator lamp on the dash to remind you might be a very good idea.

any idea if I could just add 12v to the red/yellow wire coming out of the fuse box behind the driver's kick panel in the 16 pin plug? Or is that reverse signal meant for something else?

use an ohm meter to confirm it is the same wire as the one at the back up lamp

if it is the same color as the wire at the lamp, and the ohm meter test confirms it, then the answer to your question is yes
