Here is the thing that you guys need to understand about the AUX switches...
The wiring can be hooked up in ANY fashion that you want. If you want Yellow to connect to Red like most prefer, you can do that. If you want Yellow to go to the Green, you can do that too. You can criss-cross it however you want to to make it fit your application.
The thing that you need to remember and realize is that the yellow goes to the red because they are the same wire gauge. The blue would go to purple or something, the green to the brown, whatever. I forget.
But you CAN do it however you want.
Second thing to remember... The rated amperage/fuses for the AUX 1-4 switches are only rated that because that's what the fuse that Ford put in is rated at. You want to make AUX 1 rated less? Swap the fuse from 4 into 1. Want to make switch 3 the highest? Switch 3 and 1 under the hood in the fuse panel.
You can do them ANY WAY you want -- only you can decide that.
To get your AUX 1 to work for your cutout, you first need to get behind the glovebox. There, you will find BOTH the leads from the AUX switches AND the leads from the engine bay.
Yellow is from the AUX 1 switch. There is also a Red coming from the engine bay. Hook those together and your AUX 1 switch will now power the Red wire inside the engine bay. Use the Red wire inside the engine bay to hook into the positive feed for the cutout. Ground the cutout at a location you prefer.
Got it? Let me know and I will draw a picture, but beware that I'm no artist!
When switching fuses around...what happens if you put the 30A fuse in a spot only wired for the 15A...i know ford used different gauge wiring,...
That will cause a fire.
i wired a light bar to my aux 1 and all the pass through wires from the engine bay to the glovebox seemed to be the same gauge.
After reading mudputter's thread, I still don't get it...
Here's what I want to do: I am going to install a single DMH Electric-Cutout and instead of using their toggle switch, I want to use AUX 1 for this function.
YES, I realize that using the AUX 1 Switch it will be either fully open or fully closed and I sacrifice the ability to vary the amount of opening/closing... that's okay, I had a 2008 Z06 with dual cutouts, and after the first few times playing with the switch, I was always full on or full off and nothing in between.
So the wires as is from Ford, nothing is "ready to go", right?
Why do the wires that are pigtailed together need to be spliced in the first place? The video mentions something about "arcing", but are they just being spliced and shrink wrapped for safety?
What do I need to do to get AUX 1 switch to work for my DMH electric cutout? I really need someone to spell it out for me so that I can do it myself, or guide the muffler guy to do it for me (when I say muffler guy, I mean Vengeance Racing in *******, GA who did my Z06).
Do all the wires have to be soldered first? Or just the one I plan on using?
When connecting to the DMH electric cutout wire, does that connect to the wires under the hood or the ones behind the glovebox?
