Radio Installation Made Easy
Advance Auto has finally started to stock the Metra AutoWorks radio harness adaptor to install an aftermarket head unit into the dash of the 88 and older cars with the premium sound system. It adapts the radio to the wiring harness in the dash and bypasses the amplifier in the trunk.
Part number is: CK-WHFPS
The package only lists the Tech line to call if you want to find out which vehicles it will work with. I called about my cougar and he told me 88 and older with the equalizer premium system. It may fit more but you will have to call the following number:
