    Hello all, we're working on a new wiring harness that will hopefully help people out here! We are working on a harness that will allow you to have a plug-and-play solution to run auxiliary lights with a flip of your hi-beam switch. No more turning on your high beams and then fumbling around for another switch!

    That said - I now have a handful of questions for you, and would greatly appreciate your input, use case, application scope, etc as well as any other feedback you might have!

    1) We plan on having this harness be switched. There are going to be times where you can't have or don't want the aux lights to come on every time you hit your high beams. For this switch, would you want it to be Auto/On/Off or Auto/Off? The potential "on" would allow the aux lights to be powered on regardless of where the headlight stalk is.

    2) We want to make this as PNP as humanly possible, but since it is sort of a niche product we have to develop around installing this on multiple different makes and models. There's 2 ways to tap the high beam circuit. First is intercepting signal on a wire that goes hot when the high beams are triggered (of course we'll have to account for those vehicles which are ground switched), and the second would be to leverage an add-a-fuse on the high-beam circuit within the fuse box. If the kit included a self-stripping/insulated T-tap would you be willing to use it? Or would the intercepting of your OEM hardware keep you from using the kit?

    3) Would you be wanting to run one set of lights with this, or will you be trying to turn on a Xmas tree once this is kicked over? Just trying to determine anticipated load.

    I suppose I'll start the discussion there... And if this uncovers more questions or use cases we'll go from there!

    Appreciate everyone's help!

    I know there are mods out there for this, but would stock fogs be an applicant? I know this isn't an aux lighting feature for most.

    There would be no reason that the kit in development couldn't be applied to your fog lights, but you would be rendering your OEM fog light switch useless. A "fog-light anytime" mod would be a more simple/inexpensive solution to having the fogs come on whenever.

    Cool, kind of what I figured.

    Speaking of which - Is there a write-up on a fog-light anytime mod for the 2.5G Tundras? If not I should probably toss one together. It's relatively simple to knock out.

    Yeah, I've some across it before and there are a few on YT. I think it also applied for the 2nd gen as well?

    There are a couple. The position/orientation of the relay changes depending on year though, with 2014-2017 being one way and 2018-2021 being another.

    Just sell everyone SP9100s and get them to use the high beam as one of the triggers... :spy:

    Of course that was my first thought... I know that's not in the cards for most though.

    Useful! I have my main front lights wired like this, with a tap off of the fuse in the engine bay. Three position switch for sure - Auto, on, off
