Where to find reverse light wire

[TimeOutside]

I'm in process of installing a 7-pin trailer connector on my 2024 Hybrid (Lariat). I understand the reverse light wire is coded gr/br, but where the heck do I find it? I'd like to tap into it before it splits to the two backup lights. I could tap into it at one of the lights, but I fear having three lights on a single light's wire might be too much and I'd blow a fuse. Can someone tell me where to find the wire before the split?

Thanks,
Andrew

It'd be on the same circuit regardless. And technically there isn't a fuse anyways.

But to answer your question it runs as a single wire from the BCM down the passenger front door sill, beneath the passenger seat, and splits beneath the driver's seat.

It sounds like it would be easier and just as effective to tap into it at the taillight. Is that correct?

I tapped mine behind the rear seat. Small bundle of wires exit the rear wall on the drivers side. Not sure of the color as mine is still in the shop going on 4 months waiting on a wire harness

On mine (also a Hybrid Lariat) I picked up the reverse light wire (wired into the 7-pin connector) from the Maverick LH tail light. Spliced it into the wire right behind the light, make sure you make clean connections and heat shrink appropriately. And use proper protective sleeving and zip ties everywhere.

This way you can still remove the taillight down the road.

No issues with the reversing lights from the trailer being added, the Maverick's software (and fuses) don't seem to care. Works great.

Cheers!

I tapped into the wiring on both my tail lights...so that if I ever had to undo any mods in the future it would only require replacing the short harness on the lights themselves, nothing touched on the main harness. I added weather-tight connectors so the lights could still be removed.

....and by tapped, I make 1 cut in the insulation only leaving the factory wire uncut, spread the cut, wrap my new wire around the newly exposed wire, solder and wrap with quality electrical tape. If doing multiple taps, stagger the cut/spread/solder so they don't line up so there won't be a large bulge of joints or possibility of crossing electrical paths.
