I have a 2015 Frontier (automatic). Anyone know if there is a fuse in the cabin for the backup lights? I'm wiring a backup camera and the mirror needs that lead.

In the engine compartment, it looks like there are two separate fuses I could use. Could anyone confirm that I have this right / wrong?

F21: REV LAMP IGN: I assume the normal reverse lights? Anyone know why it has IGN on it?

F16: TTOW REV LAMP: Trailer wiring reverse lights?

Thanks!

For anyone else with this issue, the electrical tech at the local nissan dealer said there is no fuse for the backup lights specifically and that I need to hardwire the power from the backup light itself.

Yesterday I tried using a tap-a-fuse on both F21 and F16 but neither worked... both had constant power regardless of whether in reverse or not. I guess that confirms what their tech is saying.

Passenger kick panel has the wiring for the trailer wiring. I'm pretty sure there is a wire in there for the reverse lights. I think one of the trailer tow relays may be for the reverse lights. That gets you reverse power in the cab. And if you go back to the trailer plug, reverse lights for the camera without messing with your regular backup light wiring.

I was working on adding additional backup lights and accidentally shorted the hotwire to ground. I knew it had blown a fuse but the Users Manual was not helpful. I drove to the nearest Nissan dealer and talked to the guy at the parts department. He had made the claim that there was no fuse as well. However, I pulled the fuse panel out and found the F21 was the issue. This is located in the larger fuse compartment under the hood.

you need to be on lamp side of relay
So how do I do this? It makes sense, but I don’t know how to find this after relay wire? For the record, mine is a 2018. I’ve just installed an Alpine IWX-650.

I'm running into same issue and spent hours Googling. Last part of my camera install. Can see out camera in diagnostics screen just doesn't trigger in reverse. 2015 frontier automatic. What did you end up doing?

I am in the same boat. 3 days, poked holes in every blue/silver wire on passenger and driver side. I started looking at clips and wiring diagrams but it doesn't show the routing through the truck. The rev lamp relay wires are really tight so i don't want to tap into them. I am running out of options and now I am looking around my shifter.
Its frustrating because all of the pictures posted where people found the wire in-cab are either expired or have no details.

Yes lesson learned for me although hopefully won't have to do this project again. Should have tested camera in cab before running wires. Then I would have known I need to run another wire from the tail light along with the original wiring sent by the vendor. Trusted what the vendor said about not needing to tap into any wires. Not going to poke around just going to run another wire along the same route I already have. Would have been nice to find wire in cab. You know the wire has to get to the back somehow!
