2020 scout high beams

[Tuscani922]

Hi folks,

I am hoping someone might be able to point me in the right direction on my frontier scout. Since the scout doesn’t come with high beams, I installed a light bar which I wired to the high beam wiring, with use of a relay (same automotive style that you would use of installing HIDs). My scout was missing the relay in the relay/fuse box, so I added that as well. My issue is that once I turn the lights on(low beams) the high beam indicator on the display and the light bar come on. I have tried disconnecting my setup, but as long as the high beam relay is in, both circuits are on. It’s almost like my multiposition switch is simply shorted out and doesn’t actually have a separate switch for the high beams.

Any ideas?

Just a suggestion, you can pickup a light bar wire harness, $15 maybe if that, for a led lighbar. It comes with a relay and switch, wire it to a keyed power wire and your done. Search NILIGHT wire harness on Amazon. Harness will work with any light bar or pod light setup. Simple to do. Then you will have your stock setup the way it came, and a light bar with its own switch. Just an idea.

Hi Grizzly! That is actually the relay I used, but simply didn’t use the led light bar switch, and used the output of the high beam wiring to trigger the relay. I was hoping I just missed something obvious or easy to rectify so I wouldn’t need to install the third party switch, but will go that route if I can’t find the solution. It would be nice to be able to simply use the existing. I was hoping someone had done this before and ran into this. Judging by lack of replies, I am gonna say not many have tried lol

Hi, It sounds like from whatever you did, it’s just sending 12v to both lights. I don’t have my 6x6 in my hands yet but I bought it and am waiting for dealer to get some accessories in because it’s a little ways from my house.just want to go there 1 time and get it. Lol. I’ll be putting lights in the way I mentioned to you. You may just have a wire wrong on the back of the the hi low switch. 12v has to go to low beam then ground for low beam function
12v has to go to high beam then ground for high beam to function the switch not wired right could be your problem too. I put these things on all my atv’s and stuff. Never had to explain it. I’m trying. Lol. Yes the forum seems slow but I guarantee theirs some smart guys in here. Just gotta be patient.

Hey Grizzly,

I haven’t changed the multiposition switch at all or any of the stock wiring. I use the high beam connector at the headlight position to trigger the relay provided with that light bar kit. No other wiring is modified. My problem is with the high beam relay installed, both the high and low relays (in the relay box under the hood) activate when moving the multiposition switch to low beam, as does the high beam indicator and the light bar. Changing to high beam makes no difference. I am thinking that they might have simply connected the high and low beam switches together since the high beam switch does nothing in stock form.
I am hoping a dealer might be able to chime in or if anyone has the wiring diagrams for 2020 frontier scout 700?

That relay stays on that harness, then you remove the wires on your little red round switch, (that came with harness) those wires will go to the high beam spot on stock switch. Then you should have a red wire on harness with an inline fuse, that red wire will either A~ Go directly to battery (Light will come on with machine off. Or B~ you take a test light, connect test light to ground, turn key on, find a wire that has 12v with key on, no light with key off,and wire that fuse red wire to that. You can use what’s called a posi-tap connector. Pretty cool connector for tapping into a factory wire. Then the black wire will go to a ground, black wire on battery. I think putting that relay in the factory fuse box is an issue. I do not know what the light switch looks like on dash but if it says hi/low then their should be open connectors on back of switch. If this thing was in front of me ide have it done in 15 minutes. I’m new to these forums. A true rookie. Lol. I always say, any bit of help is better than none at all. Good luck

Hey Grizzly, no worries, I am also a rookie, as I just bought this unit and haven’t had one before, so I only just started discovering the followings for the Argo lol. Like you said, any help is awesome!

Let me try to clarify what I have done and what I am thinking to hopefully make Sense for any reading. A switch is a switch and is used to do nothing other then pass current through the coil (of the third party relay) to activate the third party relay. The idea of the extra relay is to isolate the device from stock wiring in case of high current draw that the stock setup can’t handle)
The relay that came with the harness kit is a simple 4 pin relay, meaning two pins are the n/o and common, and the other two pins are the coil. I have ground to one side of the coil (straight to battery -) and the other side of the coil comes from the +12 that comes from the high beam connector. The connector that plugs into the harness relay just directly connects the black from the light bar to the same ground as the relay coil. The positive from the battery goes through the fuse you mention into one side of the relay (n/o) and when the relay activates and closes, passes power to the final pin of the relay giving 12v to the red wire of the light bar. My only change from stock is adding that Relay in the fuse box. I used the exact same relay part number as the other 4 pin relay in the fuse box. For some reason, turning on the lights to low beams activates both fuse panel relays, which in turn activates the third party relay I installed as 12v is now applied to my coil. I am not sure if I am explaining this well. I am almost tempted to draw what I did in Visio to ensure I am making sense to people reading lol The switch that came with the relay harness is annoying as it’s wiring harness simply jumpers power from the source to the switch’s led, meaning it would be on all the time unless I cut the standard wiring for the switch and fed the led with interrupted power from elsewhere.

Did this clarify at all?! Lol this is a terrible first thread I know.. I will make up for it with a pic intro thread after I solve this lol

[Grizzly10]

The only reason that little red switch will be on all the time is because you have the black and red connections with the eyelets to the battery. ....... The red wire wire would need to go to a wire... that has 12v when you turn your ignition key on. No power when key Is off. That solves the little red light problem period. I would take that relay out of fuse box. And work with just the harness doing what I tried to explain. Lol. You need a test light. I actually started to crack up laughing. With the Did this clarify at all? I’m more confused than ever but I could fix this in front of me , I’m a doer not an explainer��but I’m trying. Hopefully someone who can better explain it saves the day or gets a good laugh. Lol. It’s all good.

[Tuscani922]

Lol I know what you are trying to explain, but my relay harness is pre-fab, so it’s pretty self explanatory lol for some reason they just jumpered the 12 volts across the switch for the led, which is dumb, but was a non issue since I wanted to use the factory switch. Anyhow, once you get your Argo, any chance you (or anyone else with the new frontiers) want to try putting the accessory relay in the high beam relay spot and test my theory that the multiposition switch is simply jumpered across hi and low beam? The high beam indicator would come on when you turn on your low beams.

[Grizzly10]

I’m going to definitely look at it. I have lights already that are going on it. I got the baby 600, should be the same I would assume.

Hopefully I can help a little here since I went down the rabbit hole with the high beam electrical on my unit.
I have a 2022 frontier and I wanted to wire up a light bar to my high beam selector on the bars. So I tapped into the the existing high-beam plug and added a high beam relay and fuse. But I would get high and low beam on no matter the switch selection. After many hours chasing wires in the harness I found out that in the fuse panel there is a fused marked frontier that fuse is used as a jumper.
Once that was pulled all worked as It should.
Hope this helps someone down the line.

[Tuscani922]

Hey Patfera! I was reading about that somewhere else too, except someone else used a diode that is in shape of a fuse to go in that spot. Does your low beams stay on when you turn on highs or no? I think the diode in that spot makes both turn on.
Thanks for the reply though, I knew I wasn't crazy
