high beam turn on light bar

[Smitty7611]

Hey
i’ve read on how some have “tapped” into the hi beam wiring to activate a relay to turn on a light bar,
with the 2020 classic, this may be finicky with the canbus, or i may be overthinking lol

is there a harness available plug and play for light bars activated by hi beams?

Thanks

Personally, I'd run a separate switch.
I tied a light bar into the high beams on my last plow (on the plow wiring, not the truck hi beams wiring) and had no issues, but it was a smaller light bar (10-12") with not much current draw. I've also tied 6" LED light bars into reverse light wiring on my 2016 1500 but I don't like the idea of adding accessories on the stock wire. Will it work- most likely. Will FCA screw you over if there's an electrical issue and they find tapped wires- your guess, but on a brand new truck I wouldn't risk it. Most light kits come with a relay anyway, may as well do it properly.

On my 2500 I have a 20" Sylvania LED light bar that I ran to the upfitter switches (which are phenomenal by the way). If I didn't have the upfitter switches, I would have probably gone with a wireless switch into the cab rather than tapping into the factory wiring.

I'm running my light bar and a set of cubes off my high beam circuit on my 2016. I also have a switch to disable it (and just run high beams) when I want to. I am using the high beam circuit to operate relays and have diodes in place for protection of the circuit. I also have stand alone switches for each of the lights as well. I have never seen a plug and play "harness" to do this.

Relays are the the way to go. Do not rely on the high beam power to run the lights.

On my '14 Jeep I had my 2 pods relayed to the high beam. All was fine until I got LED headlights, the voltage draw change would cause the relay for the to chatter. I even tapped after the "anti flicker" module and still chatered. CANBUS sucks IMO.

Then I went to having 50" light bar, 2 pod up front, 4 pods on back, I just went with a switch pod. The aux switches were a high priority when I went looking at trucks.

I have it that way on mine. 4 switches control my lights up top that are a dual beam pattern. Left switch activated the high beam on feature, second switch is the master on, third and fourth activate the spot and flood separately. I used diodes in line so that none of the switches feed back into the system. I ran a signal wire all the way to the drivers headlight to find the high beam hot wire.
