I'm trying to wire up some extra led back up lights my truck and want them to turn on with my truck in reverse and also with a switch in the truck. I was trying to find a fuse that powers the back up lights so I can splice the wire into the box instead of to the wire in the back of the truck. The harness I have together has a relay and inline fuses to protect my wiring. Just can't find a fuse labeled for reverse/backup lights. TIA for any information you can give.
I do believe that is on the same circuit as the rear brakelights and will, on nearly every vehicle, be on a fuse with the turn signals and brake lights. I hate to be the voice of reason, but I think you will be best off running a separate power wire and having your reverse light wiretap power on a relay (depending on how crazy you're trying to go here)
96? my 95 F150 #5 under hood, do you have trailer tow wiring also, relay under hood for mine, #7 under dash is turn lamps, #17 under dash is brake lamp

Reason: more
I have a harness that currently has leads to the rear lights and to the battery with a relay to turn on from the press of the switch. I'm trying to add the ability for them to come on just by putting it in reverse instead of having to remember the switch everytime. I thought of removing the switch and just wiring that part of the harness to the reverse lights but like the idea of turning them on separately as well. So I'm trying to run a lead from the lights or fuse for the lights to the positive wire for the switch so my lights will turn on with my reverse through the same side of the relay as my switch that's wired to the harness already. This is the harness
I think I do but I don't use it so I'll have to check and I'll test that fuse tomorrow at work. Just couldn't identify one that says backup or reverse. I definitely don't want them to come on Everytime I press the brakes either. As funny as that would be that would be kind dangerous.
a few members have the strip- light LED, that does brake or reverse, if you know a little about electrical wiring you are going to have the selector switch and reverse lights(switch) in parallel so they come on when either switch is used? make since? so you will wire the reverse lights with the selector switch
The pods I have are straight white light. I just want to add a wire to the switch side of the relay so they come on with the reverse automatically or with the switch. And only automatically with reverse as I don't want to blind people driving down the road. I just figured since my relay is close to my battery and my switch is in the cab I'd run a wire from the fuse that provides power to the reverse lights so it would use less wiring than running one all the way from the backup bulbs all the way to the cab.
Underhood fuse #5 has power for more than just reverse. It looks to be tied into my turn signals. Guess I'll be chasing a wire as there appears to be no fuse for just the reverse lights on this truck.
My problem is I have power all the time to fuse number five not just in reverse and the turn signal fuse will turn the lights on every time I use my turn signals and I only want them on when the truck is put in reverse
Nevermind had a duh moment. Fuse is upstream of the switch for turning on lights so of course it'll have power all the time. Guess I'll be wiring a power wire from the wire between the switch and the light after all. Apologise for the confusion.
