High beam wiring?

[RiverRatMatt]

You can't move around the grounds at the relay. It's a series circuit that changes ground and switches to parallel with the high beams on.

The grounds are all switched with low beam activation. Which then swaps the highs to parallel.
I wouldn't mess with the daytime running light relay too much.

Okay... what wires am I checking then? Sorry I'm not understanding :/

Or are you saying I should check them by poking through the insulation ??

I would unplug the passenger high beam connector.
Turn the high beams on.
Verify 12 volts on the connector with both leads on the high beam connector.

Then move your black probe to the relay with your red probe still connected to the high beam connector.
Find the right ground with you black probe that shows you +12vdc. Either poking the white blacks or following the white blacks until you get to the bolt where it's actually grounded by the daytime running light relay...edit


Actually that won't work, following the ground. You have to get it on the input side.

Splicing behind the high beam connector will get you the same thing.

Or a splitter

Well I did some testing before giving up for the night. The 9005 connector always has 12v as long as the low beams are off, so I can't use that ground. I wasn't able to do any meaningful testing with the relay or the wires going to it because I didn't have anybody to move the stalk for me, and I don't want to poke through the wires at this point.

At this point I have no idea what to do to fix it

I totally spaced this.
I'm realizing now that the high beam circuit is going to have volts and ground when the daytime running light are on and the high beams are on.

you only want the aux lights on when the high beams are on and NOT when the daytime running lights are on. ID there no one else that has done this on here?

there still might be a single ground you can get on the running light relay. I'm not sure.
you could still wire it up that way and see if the LEDs even light, or flicker or one side lights up but the other one doesn't. That's going to be individually dependent on the lights themselves. Then when the high beams are on they would be in parallel and getting full voltage each.

you could have the fog lights on anytime wire thing and just keep them on that circuit.
Other than that I think you might have to be creative to make that work like you want it to.

lol, no worries! I probably sounded like a dummy

I will keep checking wires with my clamp meter to see what gets power with the switch. There has to be some way to do it.

I really appreciate your help, sorry I was frustrated and a bit curt last night.

 

[jerryb]

No problem. I didn't find it Curt.

If you have any headlight wiring questions send me message. I've spent weeks on the 100 headlight wiring with led issues and fixes.

I'm want to put two of my auxiliary front lights onto my high beam circuit. The question I have been pondering, however, is where to wire them so the high beams turn them on. From what I understand, the high beam lights are used as the DRLs, just run through a resistor to lower the brightness. When the high beams are turned on, the resistor is bypassed somehow. I'm assuming I can't just wire the relay for the aux lights into the high beam fuse, because it would always be on (aside from when low beams are on).

Where should I wire the aux lights so they turn on with the highs?

According to the wiring diagram, the red-with-yellow-stripe wire on the passenger highbeam bulb connector will be +12V only when the high beams are on. This wire is grounded when DRLs or low beams are on.

Tap into this wire to power your highbeam-only aux lights, or a relay that controls them. You can ground the aux lights to any part of the chassis, it doesn't have to be grounded to the same connector or to any ground wire for that matter.

This wire is also at the DRL relay on pin 5 of the 6-pin connector (same wire color), but that's above the brake pedal far away from where your aux lights will live.

Have anyone figured this out? I want to do the same.
I was thinking on finding the cable on the steering column that carries the signal, but don't know if it is ground switched or + switched.

I'm a bit rusted on my electronics abilities, I used to be an electronics technician back in the 90s now I can't even remember the resistor color code. Anyway, I can probably figure it out eventually, just want to know if anyone already did it so I don't have to start cutting cables unnecessarily.

My post #28 identifies the wire(s) you could use to control a relay, although I haven’t done it myself. Do you need specifics on how to wire the relay and/or lights themselves?

Thanks. I can wire the relay. I actually have the pods already working with a push switch, but I rather have them with the high beams.
I might put a 3-way switch to select between high beams o pods alone. Need to figure out the circuit.
