    Link Fogs with DRL?

    Hello everyone. I replaced my halogen fogs with some very bright, high-quality LEDs (completing my 100% LED conversion) and because I have the Platinum LED headlamps on a non-Platinum, I no longer have functioning DRLs. So I thought maybe I could wire the fogs to come on when the DRL function is activated. Anyone with wiring experience able to tell me the easiest way to do this?

    For reference, the actual DRL function is still actively running when I'm driving, but the Platinum headlamps don't use that signal for the DRL. So they don't do anything.

    Is there something I can do without cutting/splicing? Also, if anyone knows how to do this with the low beams I would consider that instead of the fogs as well. I just want either the fogs or the low beams to function when the DRLs are enabled, and I'd like to know how to do this in the simplest manner.

    You can do it with an 87 relay that can be purchased at any automotive store and there are many styles.

    Terminal 30 is the 12v source
    Terminal 86 is the DRL trigger (which would have sent power to the DRL's)
    Terminal 87 is to the lights (the lights you want to run for DRL's)
    Terminal 85 is to ground

    I don't see how you can do it without cutting or splicing unless you had "Painless Wiring" fabricate a harness for you.
