Toyota Aftermarket Switch Illumination Wiring Explained

In a previous video, I explained wiring for connecting an accessory to a Toyota aftermarket switch, but I didn't really go into too much detail about how to illuminate the switch at night.
Here's a closer look at one way to illuminate wiring for Toyota aftermarket switches.
Toyota aftermarket push switch: amzn.to/3DplGyc
Wire stripper with crimping tool: amzn.to/3gXn6IE
Add-a-Circuit (Mini Fuse): amzn.to/3ztI1JU
Mini Fuses: amzn.to/3DNgTZ4
T-Tap connectors: amzn.to/3Nio3aO
Bullet connectors: amzn.to/3FuASNa (alternative to T-Tap)

Great stuff thank you.

[@jawidafshar7234]

So very clear and helpful, thanks

[@LiL13izzy7]

Glad you found it helpful

Instead if the add a circuit routine, T-tap into the dash illumination power + wire. Easy peasy.

[@LiL13izzy7]

Sounds like you selected a fuse that's always on. Have you tried the fuse for the brake light like I did? Even though this fuse technically is always on, it comes on when the headlight lever is activated, thus the LED light only comes on when the headlights/tail lights are on. Hope that makes sense. As long as your switch's LED light is on, it will draw battery power, so I'd find a different fuse to work with.

You tested grounding on that bolt in the door jam, but where did you ultimately ground the wire? Thanks in advance!

[@LiL13izzy7]

Check the 10 minute mark of my other video here:. kzbin.info/www/bejne/a4myk5uDhpWqedE There is a convenient grounding screw in the FJ in about the same location.

Asked on the other video. I’m using a bussman relay box so there’s only one wire coming in for the accessory (red 1). In this case, am i missing something, or can both green and red 2 go into an add a fuse? Thanks for this video. This is about the 7th video I’ve watched of yours to juice my FJ.

[@AlchmstDsgn]

Yo! I did this tonight and it totally worked. Ran my relay wires through the fire wall, and then fused the green and res2. Ran them to an add a circuit. Golden.

[@ManuelGarcia-ui9zc]

Hello, this same process can be done for a 4 runner with the additional switches that one wishes to put.

[@LiL13izzy7]

Yes

[@ap.bb6]

when I ground my switch the on/off illumination works in opposites - is on when switch is off but off when you press the switch in. what could be causing this issue? thanks

[@punjeet8347]

I have a problem but I think it’s because I didn’t ground the cable, the switch has no backlight at all but when you press to turn on and off it works I have 2 harness but have slight back splitter to run them they arnt both the same brand though. I tried plugging the other switch onto the new one and I got light

[@LiL13izzy7]

There's 2 bulbs in the switch (one for on indicator, the other to come on with your headlights. 2 different cables. Make sure you didn't mix them up.

[@punjeet8347]

@@LiL13izzy7 the harness is a quick connect so it’s plug and play already if I can upload it would be easier to show you but it doesn’t require any joining etc with this harness from stedi

[@itsdarkest]

When I turn my car off, the led on the switch stays on while the lights are off. Two questions, what have I done wrong? And will this drain my battery or is the draw from the LED insignificant?

[@attnielthomas7856]

Hello, first off, I am not an electrician (spoiler and sorry) sounds like you got your wires crossed somehow. I believe you are working with three or more wires and crossed your relay or even merged with the power wire. Yes, it is slow draining your battery, period. I recommend using a small battery or voltage tester to determine which is your 12volt source wire and other should be your relay wire.

[@mikesweeney5685]

I’d like to add an OEM style gag switch that says “Machine Guns” to my 2015 4Runner, lol. I’d like it to light up the text when my dash lights are on, and light up the machine gun image when I push the button on. Do I connect the Green & Red 2 wires to the Add A Circuit and attach the Black wire to a ground bolt? And just leave the Red 1 wire unattached? Like your videos as they are very well made and instructive! Subbed.

[@Robwho58]

@@mikesweeney5685 I see you never got an answer but it seems to me that would work. I'm sure you have tried that by now so what happened?

[@lawrencerwall1887]

SO....How is this switch "wireless ??????????????????????

[@LiL13izzy7]

It's just the custom text I decided to put on the button. At the time, I anticipated that I would route the switch to a wireless charger I would have installed, but never did.
