Thanks for sticking with this big-foot and conferming what can and cant be used.. I too wish there was an easier way.. at the time I just didnt fell like waiting another 4+ months to get IUP
if someone can find the Wiring schematics for the 05/06 mustang I can figure it out, this is a wire change at the headlight switch, and a diode crossing over to the white led wire for the Dash Dimmer. I have the My Dash color so I can't do it on mine, but get the schematics for me and I will try.
