Help locating a headlight illumination wire...

Hey guys, thought I'd ask a quick question....Im going to need to find a wire that is powered when you flick on the headlights/sidemarkers somewhere inside the cabin (2012 JKU.) Preferrably in the drivers side dash area. Any ideas?

Yea, I would like to light some switches, but need a source without having to wire all the way under the hood.

behind any of your lower dash switches is a illumination wire if the switch lights up at night.

technically those are tied into the dimmer as the voltage will change when you rotate the dial on the light switch stalk... i would not advise "tapping" those to light up something else...

On the passenger side in the kick panel there's a wire. Have to look it up.

Parking lights (+) white/orange or white/purple in passenger kick panel. I suggest you drive a relay with that instead of connecting whatever you're connecting to it.

I just installed an switch set in the Rugged Ridge A-Pillar mount this weekend. My source for an illumination power wire was the bundle that runs to the door. The wire is Orange/Gray. It works great to light my OTRATTW Contura V switches and they dim with the dash lights. This was much easier for me to tap into than tearing the dash apart. Be sure to ground your switch lights seperately too. Hope that helps.

This is exactly what I need it for. It will basically light 6 leds which draw no power, so Im not worried about CANBUS. I have over 100LEDs tied into the dome light circuit without issue (footwell LED boards.)

So where exactly is this wire? Drivers side wire bundle that runs to the front driver's door?

Yes on my 2012 the wire lights up the power door lock on the drivers door. I tapped into it above the disconnect for removing the door.

removing the dash, on a 2013 at least, is so simple its not even funny. I have a finicky HU-Sub interface and I pull my dash at least once a week.

its a lot easier than you think. start by pulling the panel below your steering wheel, just grab the two top pieces around the bottom of the steering column and pull back, and pull the 2 bolts (maybe 1, i think the factory forgot to install one of mine) inside that secure the upper left dash. pull the screw inside the cup under your mirror next, followed by the cup (or window controls for you fancy folks) under your radio. pull the screw inside. the upper left dash should now pop off if you start pulling from the corner under the mirror.

it looks scary when you have it all out, but it goes back together very well, just be gentle and take your time.

Oh I know. I tore the entire thing apart when I re-did my audio system. I just wanted an easily tappable wire. I don't like doing things that are more complicated than need be.

Ok, I finally had a chance to install my SPOD today, and the question remains. The above information is NOT correct. The Solid orange wire on the driver's side door harness with a thin white/greyish stripe is NOT the illumination wire but the power window wire on a 2012 JKU. There is a thinner white wire with a thin orangish stripe, but I didn't try any other wires until I get some clarification.

Mine is a 2012 JKUR and the orange wire with the gray stripe was the illumination wire on my drivers door. I am positive and not trying to mislead anyone.

I don't have an Orange with a gray, I have an Orange with a white, and that is a power window wire (it is also thicker than some of the other wires.) I tapped into that one based on this thread, and when I press the window down switch, the lights on my SPOD switches come on, so that is definitely not it (in my case.) Im not saying you are trying to screw me, I'm just saying that on mine, it's incorrect. Can it be possible that we have different harnesses because you have a Rubi and I have a Sahara? Maybe we have different packages?

Edit.....sorry, you and I both might be right. You are talking about ABOVE the harness connection right? I am talking about BELOW the connection (on the part that comes off and is attached to the door.) Below the connection there is no orange/grey, just orange/white stripe and orange/green stripe I can't reach the wires above the connection.

Ok got to the bottom of it. You were right...above the harness it is the orange/silver stripe for headlight illumination. Below the harness it is the third wire over, which is the pink with the green stripe.
