I already have 2- 6" LED bars under rear bumper to add to reverse lights and wired in to come on with the reverse lights. These bars are acting up after a few years of use, (typical ebay, but hey, only paid $5 a light bar, so pretty good)
I have purchased 2 replacement bars, and can hook them up to go with reverse lights again...
What I would LIKE
to do is make the bars work with the reverse lights, AND at the same time use the wiring harness w/ switch that came with new lights, and be able to use them as work lights/ trailer hook up lights, when truck is not in reverse ( by tuning on switch)... is this even possible? Or will the Switch Fed lights feed power back to the truck badly on the reverse light wires? I am not the best with electric stuff, just basic wiring, I have added separate auxiliary lights before on their own, but not ones that also got power from truck functions
any help would be great. Thanks
If you dig through a few threads you'll find a couple guys thats have done exactly what you want.
They run the reverse wire through the normaly closed contacts on a relay, then use either an upfitter or added switch to power up the relay coil and switch the lights to a battery hot wire.
Thanks. Now I know it's possible... but I get lost at reverse lights to normally closed relay spots... is that a relay on the truck already? Or the one on the switched harness I have? Sorry, just not real experienced with this.
Go to post #2, one of your fellow forum members drew up his wiring schematic and attached it.
Thank you! I will look at this, and see if I understand it. Maybe it will help me understand a youtube vid I was looking for similar to what I want to do.
👍take you time and have some fun learning it. If you have never messed with relays before i would suggest playing with them on a work bench first before wiring on the truck. Don't forget to fuse any wire you use to tap into battery power, and your most important connection for your sanity will be a good ground connection to the frame.
under the spare tire there are actually a couple of factory grounds that you can add a ring lug to for a secure connection.
I got a 2- LED light bar harness with relay and switch in it...and tried with a separate 6" LED light not hooked to my current auxiliary. LED reverse lights... went right off the battery... it just kept blowing the in-line fuse... I hate electric work.....
