    I’m installing aftermarket dash switches to send trigger power to lighting relays. The brand of switches I’m using is irrelevant. I want one of the two LEDS in the switch to light up when the headlights are on and dim with the other dash lights. I know which terminals on the switch will accomplish this. I’m also aware that the ground side of the circuit is what dims the light. I’m looking for someone who has actually spliced into these wires and has firsthand experience with success in doing so.

    My Question; In the picture below, are these the wires and correct polarity to provide power to the “dash” lights in our new switches?

    I’ve done due diligence and read through a few threads that touched on my specific question. They were helpful in pointing me in the right direction but, as they went on the information was confused with conjecture, guesses, and comments that had little to do with the original topic. I’m starting this new thread to hopefully “unfog” the question with correct, straight to the point answers. Thank You.

    We got it all figured out and it works AWESOME! We'll finish up this weekend and have a complete install video up on our YouTube channel.

    Holy cow!

    I'll be watching that video, as I recently added a switch for ditch lights and I want to get the backlight working.

    Thank you for sharing!

    So I have a 2014 4Runner SR5 Premium, I pulled out the dimmer switch and my green wire is ground and my grey wire is power. also to make things difficult not only is it power but it is power even with key off all doors closed and interior light off no mater if headlights are on or off. Any Ideas where else I could get a dimmed wire that would be on the ignition? I also tried the wiper switch as some have used as well with no luck. I can use a wire there (I believe Blue) to get switched power for the Trigger wire however it is not a dimmable circuit.


    Follow up, So I got this figured out on a 2014 SR5 Premium, it is apparently very different from Wonderlosts 2017. Everything is opposite and I ended up using different wires and from the wiper heater switch to get all the ones that I needed, Power, Ground, And dimmer. Works great Now!

    On our Toyotas the dimmer function is on the ground side. Hope that helps you.
