In this video, I show you how to wire a Light Bar to High Beams. This mod is going on my 2020 Chevy Silverado 1500 LT Trail Boss. The light bar is on my rough country LED Bull Bar. If you don't want to worry about the hassle of running wires through your firewall or having aftermarket rocker switches in your truck then this is a great solution. I like adding my lights to existing controls that are already built into the truck. I bought the relay from Advance Auto Parts. I bought the fuse tap from O'rielly Auto Parts. I will leave a link to them below.

Ok so i’ve got an issue on my Subaru Crosstrek. The high beams are also the daytime running lights. I can’t fuse tap the high beams fuses because they’re hot. Is there still a way to have aux lights turn on with the high beams? I’m not even sure if i can splice the high beam wires at the light harness because again, i think it’s the same wire for DRL and high beams

Outstanding video! Excellent idea with the fuse tap. I do have a question as I am unfamiliar with the fuse taps. Do you think there is a fuse tab where I could run a light bar and some dish lights when the high beams are on?

@zachattackcustoms 3 месяца назад

Yes, you should be able to just tap into the high beam fuse to engage the relay to turn on the lights.

@jessemartinez9075 3 месяца назад

Thank you for this. I purchased the high clearance bumper from rough county with the same light however it has 4 fog lights on the left and right side. Is it possible to tap into the original fog light set up following your example on the video? Same truck setup.

@zachattackcustoms 3 месяца назад

Yes, you can attach any lights to your fogs as long as the aftermarket lights combined with the fog lights don't exceed the amps allowed for that fuse. I would first plug the light in and use a DC clamp meter around the Positive side to see how many amps the light draws. then I would add how many amps each fog light uses. As long as you are below the amps on the fuse, you should be good.

Great video! Quick question about the connections on the 12v relay. Bottom right is for the fuse tap, bottom left is for the direct connection to the negative terminal on the battery (or any ground, right?), and for the top 2 connections, since it's replacing the switch, does it matter which wire is connected? You've got blue on the top and white on the bottom, but it shouldn't matter right since the relay is what closes the circuit when the high beams are turned on right? I am wiring a pair of Nilight 4" pod LED's to the high beams and the wire harness w/ relay looks very similar but the wires are not blue and white. So just wanted to be sure. Thanks!

@zachattackcustoms 4 месяца назад

Correct bottom right is for the fuse tap. And yes you are correct, there is no polarity for the other wires for the closure. Thanks for watching! Glad to help!

Thanks so much for such a quick response!

On my 2020 it was easy, install the bar, hook up power and tap the high beam fuse in the fuse box, no splicing. I went to install a new bar on my 2024 Chevy Silverado and all was going as planned until I got to the high beam fuse…there isn’t one. Just two fuses for the right and left headlamps. Any thoughts? Or just install a separate switch which I really don’t want to do. It was super nice having it come on with the high beams.

@zachattackcustoms 6 месяцев назад

Dang that’s crazy, I just looked up the manual and yea, I can’t find a high beam. I wonder if they are just using the same fuse for power and then a relay to switch between the two. I will try to look in the gmupfitter website when I get a chance. I definitely recommend checking out the website. That’s where I get all the detailed schematics to figure out how I can make wire modifications.

@zachattackcustoms 6 месяцев назад

After looking over the schematics, I would check fuse F7 which is under the hood. It looks like that’s how it gets triggered. I would first check to see if it has voltage on the fuse without the high beams on.

@NeverGone23 7 месяцев назад

Any idea if your bull bar will fit a 2023? I just got a '23 and I don't see anything on their website that fits.

@zachattackcustoms 7 месяцев назад

I can’t imagine they really changed that much. The biggest part of the refresh was the interior. I would call rough country and see if it will fit.

@martinbril5619 4 месяца назад

Where would I put a switch in the circuit to have the option high beam/no light bar - high beam/light bar? Could it be basically anywhere?

@zachattackcustoms 4 месяца назад

I actually did a video on this: ru-vid.comR0TfB-BvfEM?si=Ollu8Chi2VYw1PpU

@Oneillnn 5 месяцев назад

Would the relay already provided with the light bar be fine? No need to buy another relay?

@zachattackcustoms 5 месяцев назад

You have to have a separate relay for the closure to engage the rough country relay to supply power to the light. The extra relay replaces the switch.

@stardjandkaraoke 9 месяцев назад

Does that still give you an option to have it remain off?

@zachattackcustoms 9 месяцев назад

If you set it up like this it will always come on with your high beams, but I did not try to turn it off with the remote once it was on with the high beams. I will try that and get back to you.

Hi I need your help. I have a 5 pins relay which is 30, 85,86, 87a, and 87 which one I am going to connect blue and white cable from switch that I cut? Also which one is going to fuse tap and battery negative? Thanks in advance.

@zachattackcustoms 25 дней назад

You will need to connect the fuse tap to the positive on the relay and the negative side of the battery to the other side of the relay. A lot of times the positive and negative connections are different colors than the closure connections on the relay. To find out which connections close, take a multimeter and select the the continuity mode and put your leads on two of the connections to see which connections close. You should hear the multimeter beep when the relay closure is triggered by voltage. The blue and white will be connected to those two connections and doesn't matter which one goes on which. You are just looking for the blue and white to make a closure.

Thanks for your help. It works

@aaronbandy6393 27 дней назад

do you have a link for that remote set up ?

@zachattackcustoms 25 дней назад

I just bought it from Rough Country's website.

@beardeddude2613 7 месяцев назад

I have the RC grill lights that has the same wiring harness and want to do this. However, the relay I have is a little different than what you have. The relay has 85 87 86 30. So is 85 ground? 30 to the fuse tap?, 87 white (12v)? and 86 blue the trigger wire? Thanks for the help

@zachattackcustoms 7 месяцев назад

Send me the model number of the relay and I will tell you how to wire it

@beardeddude2613 7 месяцев назад

Thank you! It's a dorman 84601

@zachattackcustoms 7 месяцев назад

30 and 87 will be your closure. So, hook Blue to 87 and white to 30. I can't find a diagram showing me which is the positive and the negative. 85 and 86 should be positive and negative. Before installing it I would hook 85 to negative side of battery and 86 to positive side of battery and see if the relay engages using a voltmeter checking for continuity. If not I would swap them around. @@beardeddude2613

@beardeddude2613 7 месяцев назад

Thank you! 20 you know Where i would use the fuse tap?

@zachattackcustoms 7 месяцев назад

@beardeddude2613 in one of the high beam fuses. Just make sure you put it in the correct way as I explain in the video

@Sandman03 6 месяцев назад

You never explained where your wireless connector was in the wiring. I would like to do the same.

@zachattackcustoms 6 месяцев назад

I didn't go over that because you don't have to have it in line with the setup. If you do want it, I got it from Rough Country for $25. It just plugs in line with the connection for the LED Light Bar.
