AC Delco head unit

if you have aftermarket colors:

red = switch 12v, yellow = constant 12v, black = ground, blue = remote turn on, blue/white= amp turn on, RF Speaker = gray/ gray&black(-), RF speaker = WHITE/ white&black(-), LR speaker = GREEN/ green&black(-), RR Speaker = violet/ violet&black(-)

if you head unit has OEM colors: (off the top of my head)

orange =12v constant, yellow=12v switch, black=ground, RF Speaker=GREEN/ lt green(-), LF speaker= tan/gray(-), RR speaker = blue/ lt blue (-) LR speaker = yellow/brown(-)

Thanks,

They are wierd, I figured it out today by process of elimination and will post them later.

Now that I have figued out the wires to each speaker (4) how do I tell what is Pos and Neg for each speaker?  I even tried hooking up the output to my fluke 123 scope and all I can tell is that it look like a variable AC wave with no apparent polarity. ???
