best way to wire cargo/backup lights in a headache rack

Im wiring up a headache rack, with two taillights and two reverse/cargo lights. I plan on using 6 wire trailer wire from the trailer wiring plug in my bed for turn, brake, tail, and reverse lighting, but i dont know the best way to get a cargo light function? Should i tap into the existing cargo light somehow, or would it be better to trace out the reverse sensor and make the reverse lights come on with a switch to have bed lighting? The other possibility would be to make another switched circuit and just run two more wires up to the lights... Which would be the best way to accomplish this?

In this type of example, I would suggest a manual switch relay from battery hot. That allows the lights to be on while you're back there, instead of turning off the lights on a timer. Caution should be used with this option, as you could kill your battery. The second best is to run a battery hot option off of a relay controlled by the existing dome lights.

I ran two separate wires from a battery hot and toggle switch them. I use them a lot so for me I had to have them on a switch.

Hot from the battery. Use an inline fuse . That's how we do it as upfitters.

So it won't hurt anything to back feed power from the battery into the reverse light circuit in the trailer wiring harness?

I think he means you will do the lights separate like you said as an option. I grounded my two lights to the back rack (just make sure back rack is grounded) and ran one hot wire with inline fuse from a constant hot under the dash to the switch then another wire to the hot on the lights. Very simple.

Oh ok, I'll just go ahead and wire these as backup lights then probably buy some led tractor work lights to use as cargo lights later on.

Run a separate hot wire. You can use the reverse line as a trigger for a relay, but don't try supplying power to large lights through it, as you could over load the wiring and make an electric fire.

Mind me asking which cabguard? Sounds like a Ranch Hand. You can run the brake lights, reverse lights and ground directly to the trailer plug. No fuses needed, as they are low draw. If you want cargo lights to work like the OEM, wire them into the OEM cargo lights inside the 3rd brake light housing. If you want them to be on a switch, run a new, fused hot from the battery, and preferably a ground too. If you need any further detailed instructions, don't hesitate to ask. If it were mine, i'd wire them to a switch.

It's homemade, looks like a ranch hand but made like a tumbleweed mfg headache rack. I was just trying to figure out a way I could use the same two led lights as cargo and reverse...
