ok, we have a 72 comet with original wiring. the previous owner installed a radio. recently the red power became disconneted for it's power source. we tried and couldn't find where the red power wire was connected. so our question is where would we connect the red power wired from the radio to. pics attached, thanks! joe
I don't see your pics, however there should be a connector under there near the radio with a black wire and a blue wire with red stripe. The black wire is the switched power for the radio. If all else fails, you can run another wire over from the "radio" fuse on the fuse panel.
Radio fuse should be the one at the top right of your fuse box with the blue stripe around it, and I can see that it is blown and has corroded contacts.
Also, just FYI, I would get rid of all of those "wire nuts"...they are just looking for an excuse to wiggle off and short something out. Use crimp-on connectors, and even better, dab some liquid electrical tape in the ends of them to keep them dry and corrosion-free. Those wire nuts are made for house-hold use, not automotive. There are also some cool little press-on connectors that have a couple drops of an epoxy or similar in them. I have never used them (kinda pricey) but they seem like they should work well.
Solder and shrink tube is the only way to go. If you want a feed for your radio, just get a test light and look for one. Pick a switched one, not a constant hot one.
I would sugest that if you use a probe type test light you make sure that the power lead is from the "acc" side of the switch. You don't want to have the low voltage going to the radio when you are starting the car.
