Wiring for 77 Scottsdale 10 radio
« on: February 14, 2008, 05:14:17 pm »
I just bought a new "Durabrand" tape deck for my 1977 Scottsdale. Anyone know the color coding for what wires are the

1:Positive
2:Ground
3:Accessory: the one that makes the radio shut off when you shut off the key?

Any help would be appreciated...

is that the same in 79? i have an old pioneer kp-500 im putting in my truck and im trying to figure out the wiring on it. i have the wiring diagram for the truck and saw that the grey goes to the fuse panel and had no idea what the yellow was for.

on the radio i have a red, black, green, and grey.
im assuming:
red = power
black = ground
green/grey = speakers?

do i just run the green to one speaker and the grey to the other, if so do i need some kind of ground too?
