Rear backup lights

[Raplon]

Does anyone know a good place where I could tap into a power wire of the rear backup lights? I have 2015 1500 Limited.

The center pin on the 7way connector is tied to the reverse lights.

Nice to know, thank you! is it possible to get to 7 way connector harness from the inside the cab?

It'll run under the cab somewhere but not into it. There's a vent on the back of the cab behind the rear seats that I usually run wires through that could get you up into it.

A lot of guys use one of these: CURT 56584 https://www.amazon.com/dp/B007EA6WQU/
Then you could run wires to the cab and back if you wanted a switch to turn them off.
The other alternative to find the wire in the harness in the driver side front wheel well. The plate that covers the hole where the clutch pedal used to run is a good place to get wires into the cab.

I am installing KDLINKS R100 mirror with a front-facing camera. It also has a rear camera included, that supposed to be triggered by switching into a reverse gear, so it needs to be spliced into the backup lights.

Can you give me a little more specific location, please?

I am aware of this hole, but the problem is I would have to run the wire from the rear of the truck to the hole and than back to the rear of the cab. Not very practical.

True, but it’s something you only have to do once, and the amount of time you’d spend trying to track down an easier one could be more than if you just did it that way to begin with.

Case in point, I have a switch on my dash labeled “AUTO HIGH BEAMS”. When this switch is activated, AND my high beams are activated, all of my offroad lights come on. In order to accomplish this, I needed a trigger wire for my high beams. I figured I might be able to find one in the cab somewhere, but there was one place I knew I could find one: my headlights. I ran a wire all the way to my drivers side headlight and tapped into the high beam wire. Something I only had to do once, and I knew it worked. Just food for thought.

Run a paired 14/2 from the back to the dash. I'm guessing your using LEDs for the auxiliary back up lights, you won't have much if any voltage drop and there's not much current either. Run the wire once and the connections are convenient. I've ran a fair bit of wire through vehicles, this would be quick and painless
The 7 pin wiring already individually fuse protected and it would be simple enough to use a On/Off/On switch to make the lights work with the reverse or on all the time (pull fused power from the battery).

This absolutely makes sense! Bringing a wire from a headlight through the hole in the front of the cab. In my case, I need to bring a wire in from my rear lights. The opening behind the rear seats sounds like a better solution here, especially because the rear camera for which the wire is intended will be by the rear glass of the cab!

You could also just grab the right or left backup lamp power wire right at the source- the BCM is right up above the brake pedal.

Don’t mean to hijack this thread but i don’t want to start a new one.

I bought LED lights that mount to tow hitch. I want to wire them up so they come on when I put in reverse. But I would also like to be able to turn them on and off with a switch in the cab.

I know for reverse lights, I should tap into trailer hitch harness. How would I go about adding a switch? I’d ideally like to add a clean looking switch into a blank space under the head unit

You will need to add a diode to prevent any backflow to one or the other power sources.

Here's good thread with switch locations

Why use diodes? They are not needed if he uses a SPDT (On-Off-On) switch to select if he wants the reverse lights to turn on w/reverse, on constant (from ignition switch source) or to stay off.

Take it easy Turbo....there’s more than one way to do things ya know.

think I’m just gonna run them to a switch in the cab. Would the wiring look something like this? I don’t need a relay right since these are small pods? What about the fuse?
