Anybody know where to grab a Hi Beam ground?

[Oldfart]

I'm finishing up wiring my pocket lights and I want to have my BD combo's switch on & off with my high beams. I'm all set except to find a high beam ground to tap into. Any one know where to find one?

I'll be waiting patiently talking on my cell phone.

ground is ground no matter what. a chassis ground is fine. or run back to the battery

I need a ground from the high beam that will activate a relay.

use the power. the lights are constantly grounded. the power is what comes from the relay. while the high beams take a negative trigger, its going to a relay in the fuse box to send power to turn it on

I'm using a Baja Designs #64-0164 2 pin Hi Beam harness with a relay. It comes all set up. The harness has the normal terminal ends, positve and negative terminals, to attach to the battery. What would be the end for the switch wire has a red wire looped back on itself and terminated, and the black negative wire has a vampire tap on it. The BD tech says that I need to find the ground from the high beam to act as the negative trigger for the switch wire.


Pro & Sport 2-pin, Hi-beam Harness-2 light max 150 watts
This universal 12v wiring harness is capable of powering up to 12 amps and has been specifically designed for our 2 pin lights, this includes Squadron Racers, Squadron Pros, Squadron Sports, S2 Racer, S2 Pros, fuegos, PreRunners, and LaPaz lights.

It includes a tap in for your Hi-Beams to provide power to the lights. This harness comes ready to power up to two (2) Baja Designs LED/HID lights listed above.

doesnt make sense. the ground from the light goes directly to chassis ground. you could use a relay to change the polarity though

That was the answer I got on the phone, after asking a BD tech specifically what wire to tap into for the "switch" wire. That didn't make sense to me either, but I'm far from a wiring pro. If he was mistaken, and I need the positive feed wire to the high beam, does anyone know which wire that is?

I just called BD back and asked more questions and now he says you could use the positive for a switch wire, but that it's not possible on a '20 because there IS NO high beam wire, it's internal. I'm so glad I already pulled the original fully installed harness out after I got his first advice when I received the high beam harness! Thanks to tech support @Baja Designs for making a bunch of needless work for me.

@FordTechOne do you know this one by any chance? Is there a high beam lead wire that can be used for a relay?

That harness is used with a traditional style headlight with three leads, low, high, and ground. On most automotive applications, power is switched between low and high with the headlight switch. But on newer vehicles such as a 2020 Ford Raptor, I believe they've changed that. You can confirm this with a multi-meter or test light probing the leads from the back of the headlight. What you're looking for is a lead that has power in the high beam, and no power in the low beam. That would be your high beam wire. But hopefully a FRF member can chime in on that and what they've incorporated. Most customers run our lights to the auxiliary switches on Raptors. If it's a switched ground design to go between low and high, that harness will not work. That relay needs switched power to trigger a closed circuit.

To answer your previous question, the red wire has 12v constant power and would be left capped like in the picture. The black is for the load (lights) and is tapped into switched power (ex. high beam circuit).

I thought I would post a picture of a pair of ******* to see if it helps me get an answer.
