Well, here is a list of the wires with labels on my harness for my old HU:
Blue: Remote B+ (turns on amp when HU turns on)
Yellow: Backup (this goes through the stock harness to a 12V+ source)
Red: ACC +B (this goes to the ignition wiring system, allowing the HU to turn on without the car being on)
Black: Ground (grounds the HU to the frame, allowing circuit operation)
Orange: Dimmer (allows the dim function on HUs to operate)
Blue/Red: Power Antenna (this allows the power antenna, if installed, to operate
Pink: Tele Mute (utilizes the telephone mute feature in higher end vehicles)
Violet: Rear R+ (positive input for rear right speaker)
Violet/Black: Rear R- (negative input for rear right speaker)
Green: Rear L+ (positive input for front left speaker)
Green/Black: Rear L- (negative input for front left speaker)
Gray: Front R+ (positive input for rear right speaker)
Gray/Black: Front R- (negative input for rear right speaker)
White: Front L+ (positive input for front left speaker)
White/Black: Front L- (negative input for front left speaker)
You will also have your pre-outs as well as your antenna input on the rear of the HU.
I don't know much about stock harnesses, due to my having always used aftermarket, but I've never heard of this 'memory feed' wire at all, ever. The other wires are self explanatory, but that one, no clue. You may want to talk to the guy who you bought the truck from or even try searching google for some answers. This is starting to appear as though it's out of my element. I'll keep trying to think of what's going on though.
