hi all.. i installed my z2 and hooked up the dimmer wire and it does nothing. i checked the wire and its hooked up and to the same wire that was hooked up to my n3. i have a 2008 f350.. i also hooked up the vss wire and most of the functions on that screen work, like the mph and volts. but a few dont work, like the direction.. does that mean i dont have the right vss wire ? or what ??
thanks..
