    I'm getting my plans in order to install a Stealth 32" light bar, from Headlight Revolution, in my 2015 Tundra grill. I plan to use all the components with the kit, except for the light switch, which I plan to get from AirOnBoard to give the install a more OEM look. My question is where is the best place to tap into the dash light circuit? I want to have the switch illuminated along with the rest of my dash/switches when I have my lights turned on. My initial plan is to tap into the circuit at a neighboring switch's location (door light switch or headlight leveling switch unless the blank switch location has wiring connector behind it for the blank) and to find the power wire by checking the wires to it with a multimeter when the lights are turned on. The new switch would be on the lower left side of the dash to the left of the steering column. That way I only have to unscrew the lower left side bolt that holds the lower dash on to gain access. Is this a good plan or is there a better place to tap into my dash light circuit? Thanks for any help!

    Pretty much every OEM switch on your dash has an illumination wire. I usually just tap off of the nearest OEM switch to where I'm installing the new one.

    I just shaved off a little bit of insulation from the tow haul button, Soldered the light bar backlight wire to the tow haul one and electrical taped it back up.

    I used a volt meter to figure out which was the back light, I wanna say it was a green color.

    A tap would probabLy be simpler but the wires were suuuuuuper little and I didn't have any on hand so I did it that way

    Thanks for the replies and pictures, Gents! Does anyone know if the blank switch locations have wiring connectors behind them in the harness?

    Is that an AOB switch you used? Looks great, by the way.

    Yes AOB, I wanna say $23 a piece. I thought I had a picture of them lit up. I did red back lighting to match stock, then the image lights up green when turned on.

    Then for your question when you pop the square piece out that has the blanks there was nothing back there, a cluster of hires maybe 4 inches away and only the 2-3 wires needed to reach the tow haul button. There is plenty of room to work with. I used a coat hanger to shove my wiring down below the dash and did most my work under the pedals since my light at wires ran through the rubber grommet on the driver side(if that's what you meant)

    Thanks for the added comments, Blake. I was wondering if the blank/unused switch locations have the wiring harness for the switch/option that would normally be in that location. Doesn't sound like it is... I'll proceed with my plan to tap into a neighboring switch illumination wire. Thanks again for all the help!

    I didn't see any extra wires behind the blank on mine. Access and install was pretty easy to figure out by using common sense. I ran my wire harness through the firewall plug, hooked up the switch to test then pushed it into where the blank was. Super easy. Just haven't taken the time to hook up the back light yet.

    best to remove the entire lower panel and unclip It from the back. Its only held by 2-3 screws and the rest are clips.

    I am guessing that the screw on the left side is behind the kick panel since someone said to take kick panel off

    I believe the VSC Off Switch, Interior Dome Light Switch, Cargo Light Switch, and Headlight Leveling Switch all have a light blue illumination wire.

    Just checked mine and the back-lit switch I used does not dim with the other switches when the dimmer control is turned.

    Just finished woring up mine. Used a fuse relay box from eBay so I could run all small wires back to the cab. Also bought the replace right panel made to house a brake controller and put a 3gang switch in it. Worked out perfect and couldn’t look any better imo.

    very good info! I bought a couple of switches to change out my stocks (better/fun graphics) now I feel a little more secure about how to pull the OEMs out and replace them.

    What about the TOW haul is that the same as well? I saw someone write above that it was the brown wire. I just hooked up my lights but that’s the only thing I haven’t wired yet.
