headlight fuse for ambient lighting?

[djevox]

it looks like the description for that says overhead console and heads up display, switch 911, switch assist, or maybe im looking at an incorrect chart?

You are probably correct, I’m going off of memory since I’m not in front of a computer anymore. Earlier today, I was messing around under the steering column of my truck and that is the two fuse slots are used for the parking feature on my dash cams.

As I stated in the other thread - simply tapping your power wire for your LED lights onto the headlight power wire will accomplish what you're wanting. They will only come on when your headlights kick on. Very easy to do. I don't believe there is a headlight fuse on the interior fuse box, but I could be wrong.

It’s probably not that simple. There are separate wiring for low and high beam, meaning he’ll lose interior ambient lighting when he switches to high beam or not have it when he switches to low beam. Some food for thought.

May I suggest keeping them on a separate circuit for ease of wiring, but use one of the homelink buttons for a clean look? Check out this writeup. It wasn't mine, but I really like the idea.

Looking to add AUX switches? Using the homelink buttons to control Lightbars DIY HOW TO for under $20.

So I just added MicTuning C2 rocklights under my truck and I didn't want to drill a hole on a panel in the interior of the truck. So I purchased a eMylo DC 12V 1 Channel 433Mhz RF Wireless Relay Remote Control Momentary Light Switch Self-lock Transmitter with Receiver for Home Use Learn more...

What? That made no sense lol. The low beams aren't turning off when you activate your high beams? Don't tap into the high beam power wire, but I don't believe that is at the headlight knob.

Take a look at the wiring diagram, and it’s not common for low and high beams to be on at the same time.

IDK how common it is, I've never seen a vehicle that shuts off the low beams when you activate the high beams. Our trucks certainly do not do that. The fog lights, yes. Those are cut off when you hit the high beams. Either way - I'm just telling you what will work. Whether you want to go your own route and make it more complicated, that's up to you lol

My low beams shut off when i turn on high beams.
my truck is un-modified (so far)

@bnh105 Firemedic’s passive-aggressiveness aside, check your truck to see whether low and high beam stay on. I don’t have access to a limited to check if there’s low beam dropout. If they do stay on, you’re good to tap into those low beam wires, but if it were me, I’d still check the lo beam voltage to see if it stays at 12v+ DC when high beams turn on.
I also don’t know if your DRL‘s will run the low beam (mine do on the laramie). If so, you’ll have to take that into account.

I've worked on a few limiteds, the low beams did not turn off when the high beams were activated. This was on a 2020.

i checked mine in a store window last night.
lows stayed on but dimmed just a bit.
fogs stayed on
oddly, i could not get the main low beams to turn off at all.
even if i turned the lights to off.

With my LED headlights the low beams stay on when I turn on the highs, best headlights I have ever experienced.
As far as tapping into some fuse, you all might be out of luck, from what I can tell they are controlled by the BCM So it would be necessary to tap straight into the head lights wiring.
This is the basic lights diag. LEDs are the same exept they are called out as a circuit board.

You are correct - they are controlled through the BCM.

your DRLs are enabled.

 

[J-barcarp]

your DRLs are enabled.

I will have to look at that when i finally get around to plugging in my alfaobd

You can disable them thru the Uconnect screen. The DRL strips however can not be disabled - at least not thru the Uconnect.
