I've had a sony Xplod CDX-4000X cd player in my truck since I bought it, but recently decided to put a computer behind the seat for mp3z, and realized I needed a deck with aux in, so I bought the Panasonic CQ-DF800U and got it today in the mail, go to install, of course the harness is for the sony, so I drive to best buy and they try to sell me the same plug as came with the unit (bare wires on one end, panasonic plug on the other) Seeing as that wont do ##### for me, I say a polite version of stick it, and go home and break out the shop light and go at the wires, just crimping the wires by color and electrical taping the ends. Get all excited and turn key to acc, nothing happens...so I turn it off and break out the voltmeter, yellow wire (battery lead/always on) to ground is .04 volts, *sonufa!*
switched lead is 0, dar, turn key to acc 12.68 volts, good. put voltmeter on the top of the harness to the yellow lead, 12 volts, but past the harness it is .04-.10 volts...what the hell is going on and why doesn't best buy sell a Ford-Panasonic harness????
