I go to install my aftermarket head unit and i get everything hardwired and sound comes out and everything, when i turn the volume, all the guages and lights flicker and sometimes the headunit says protect. There are 2 wires that were seperate from the 2 harnesses in their own harness (2 wires) they are purple and white/black... where do they go? also some wires were also questionable.. infinity amp wire (which is it?) power antenna wire, power continued wire...has anyone installed an aftermarket head unit into a 98 ZJ with the infinity system? does anybody have the ACTUALLY CORRECT WIRING DIAGRAM? installdr.com is completely wrong, and no other websites have it. do i need an adapter such as this?:http://installer.com/cars/jeep.html (part CHYAH) does ANYONE know whything about this?? I had a professioal here who couldnt figure out the problem we had it all up and running. please help me i need this installed by tomorrow.
