Ok noob questions.
Is the purpose of this mod just to have the 4 or 6 lights on at the same time while driving?
I just dont see the purpose of having the the 4 lights on at the same time, is it just for better light output?

Sorry to bump an older thread, but I just can't seem to wrap my head around this one, especially as it seems there are a few different "variations" going on in this thread. Below is what I would like to accomplish in the end. Could someone tell me if the 6 High mod from the OP is all I need to do, or point me where I can find the writeup for what else I need in addition?
I am sick of having to hit the button to turn Fogs on, every time. I want my fogs to be wired so that whenever my lows are on, so are my fogs. Now, my lows would still be wired so that they still come on based on the light sensor (like normal) or the headlamp switch (again, normal), but whenever I turn my highs on (via stick forward), my lows stay on, as if I pulled the stick towards me. Because the lows are on, the fogs are on. Basically makes fogs my 3rd and 4th low. I do not care about functionality of the fogs button.
Is the above what the 6 High mod accomplishes? Is there anything in addition that I need to do?
Thanks for the help!

I did the "Full Auto 8-High Mod" (I engineered it myself). There should be a DIY post in this thread where I walked someone through it (you can see my "Automatic, instant on" lights in my avatar).
I saw that, but is that what I need? The 6 high won't do it?
Edit: Rather, I thought I saw it, but only saw things referencing it. Could you link it by any chance, if I truly need it?

If you just want your fogs on w/ your lows, then you don't even need to do the 6-Hi mod. Just jump your relays, or tap your fog wiring into your lows.
That's what I thought I wanted, but then seeing y'alls enjoyment of all of this, I figured I might as well go the full mile, right?

I have to go to bed, but bump this thread again (reply to this post) and I'll show you how to do it my way (all out) tomorrow.
I will shoot you a PM as well, I'm in no rush. Have a few days before I'd get to it anyway. What me and my lack of electric skills are guessing is that it would work if I did the 6 High mod, then connect a diode from the HDLP-Low 85 to the Fog LP 85, with the gray part of the diode facing the Low relay. Will talk tomorrow. Thanks for the help.
Edit: After looking at the fuse diagram and writing it out, I might just try a few things to cut out redundancies but get what I am looking for. I guess at this point my question is what could I break in this process?
Do I need to worry about anything touching anything, other than involving non-85 pins? I say this because I may diode the Fogs to the DRLs so the fogs are truly 24/7, and then will have to see whether I like the look of DRLs and Lows on at the same time or not.

You can jump the relay terminals with diodes. I converted my DRLs to Amber running lights and covered my photo cell - on top of the full time fog mod. Now I have full time, full auto: Lows, Running lights (w/Amber DRLs), Projectors, and Halos (w/leds) that I wired to the running lights and blinkers, so they blink as well. I can still control my lighting: Full time, full auto with "Off", "Parking only", Parking w/ Fogs", and the 8 - Hi mod (if you count the DRLs). All in all, I love the setup. It's really effective when you're in the passing lane, or on a dark road.
So all it is is using extra diodes to includd DRLs and blinkers, as I described in my last post? By "jump the relay terminals" you mean connecting with diodes as in the OP diode? If so, all of this is much easier than I thought.
Thanks again.
Thanks again.

Yeah, it's not rocket science. You just have to understand how diodes and relays work.
Also: Don't forget that you can splice into another lighting circuit with regular wire. Just make sure the circuits have the same amperage and you're good.

You just have to pull 'em out of there. You're not going to break anything. There's no special way of doing it. I used pliers.
Thanks for the reply. Had already looked at some other forums and figured I'd just try it. Used pliers, pulled those suckers like teeth. They came out clean, no clicking or popping, just a big, sustained pull. Anyway:
Finished this a little while ago, here's how I did it in order to get 6 High and Fogs on with Lows. Works exactly how I wanted!
Prepared to test it for first time:
It works! Highs on, therefore lows and fogs on. (In Park, so parking lights/side marker also on)
Lows on, therefore fogs on (and in Park)
As always, thanks for all the help guys!

Thanks for the how-to on this ... will be trying this over the weekend. (Newbie first post.)
