Hello,
A prior owner cut the radio harness off that connected to the original factory radio in my 79. I want to install a new stereo but I am unsure which wires I located under the dash were attached to that original harness/radio. Does any one have a picture of a 1979 radio with its wiring or what color wires connect to the radio?

Thanks

Doug1

my manual, 68-82 shows (for later models BASE):
yellow: hot to radio fuse 10amp(just when key is on)
gray: hot at all times with a 7.5 amp fuse
left front speaker tan and gray wires
right front speaker: light green and dark green

system with REAR speakers
gray and yellow same as above
brown: light switch
orange: goes to ctsy/clk on fuse block 20amp
front speakers:same as above
right rear: dark blue and light blue
left rear: yellow and brown
manual does not differentiate between positive and negative for speaker connections

Thank you. question-Brown goes to light switch? What light? Whats that mean?

i assume its when the headlights in car go on, the radio will light up for easy night time visibility. remember, these were the stereos from the old days, unlike the new one's that are always lit up

Good point.

Is there anyway to look up where on the fuse block the gray wire gets pwr from the 7.5 fuse. Mine has a gray wire but no 7.5 anywhere

On the new stereos what PWR do they use for keeping clock current ahd radio presets?
