Rear Bumper LED Cubes

[Cjcolyer]

I have a 2020 Rebel and recently installed the rough country rear bumper that came with 2 LED cubes. I’m trying to wire in the cubes to my reverse lights so I can completely bypass the switch that came with the bumper. Does anyone know of a good method to go about this?

I thought about tapping into the 7-pin, but I hear some people have issues with their truck thinking there is a trailer attached when there isn’t.

I also considered tapping into the power going straight to the reverse bulbs and just adding an in-line fuse.

Use a fused relay and use your factory reverse wire as the trigger for the relay. Works 100% and won't have to worry about overloading your reverse circuit.

Would running an in line fuse for the cube without a relay overload the circuit?

Likely - simply adding an inline fuse doesn't do anything to lessen the draw on that circuit, that's what you're needing the relay for. It'll be drawing power from your main fuse box (which is where I recommend you grab power from). I tried wiring in some small LED pods on my dads truck that has the halogen stock lighting without a relay first. As soon as we'd put it in reverse, the new lights and the side I tapped into on his reverse light would go out. Once I installed a relay, they worked perfectly.

Alright, makes sense. What amperage was the fuse you used for each cube?

You'll only need the one fuse that you'll install at your relay power source. You'd have to check what your cubes you buy are rated at, but a 20 amp fuse I'd think would be plenty.

Alright I’ll give it a shot. Thanks for the help!

UPDATE: I ended up just tapping into the reverse light wire in my 7-pin and they work fine. A tad bright, but they work.

Hm, I'm surprised they're not causing any issues with power draw. Do you have factory LED lights or halogen? I did notice on my 2021, I tapped just right into the reverse signal with no relay and they worked fine. But on my dads 2023, that has halogen lights, tapping direct to the reverse signal caused issues.

I bought my truck used and got under it to install some AUX reverse lights and seen a previous owner tapped into the 7 pin. Needless to say I took that off and soldered into the wire and no issues for me either!

My original plan was to use the curt harness and go that route but plans changed once I seen that b.s.

I used the 7-pin adapter, Deutsch 2-pin splitter harness, and 2-pin Deutsch connectors to connect mine. 7-pin adapter and splitter harness orders from @VICE design. My DV8 light pods came with Deutsch connectors.

Using the 7-pin harness wiring there is no worries about "overloading" the circuit. It's designed to power reverse lights on a trailer without any need for a relay. And LED lights have lower power draw than halogen. I imagine the issues with your dad's truck had more to do with the lower resistance of the LEDs compared to halogen, or poor wiring

All of my lights are LEDs. I have a 2020 Rebel, so I think that’s the standard on them. Only thing is they’re unnecessarily bright. lol

Unnecessarily? I mean, compared to the weak factory reverse lights, sure. But at last you can see behind you backing up now

Definitely not poor wiring - I've been doing upfittnig on the side for the last almost 13 years. I'm OCD when it comes to neat, clean wiring lol. I think the issue actually was caused by me tying into the actual taillamp reverse circuit as opposed to the 7-pin reverse signal. I believe on my 2021, that's actually what I did and grabbed power direct from the 7-pin, so that makes sense now.
