Radio Wiring

[Canadian1968CoronetR/T]

OK, weather finally got a little warmer, thought I would look at putting my Refurbished radio back in. The fellow that did the refurbishing said the orange wire on radio was for a external dvd player etc. I did not need to use it unless I was going to do this, I am not at this time.
Now for the question, I do have a orange wire coming with the red radio wire from car, what is this for?
Should I follow what my radio guy told me or hook orange to orange.
Right now I am leaning towards what he said and not hook it up.
What do you guy's think?

Thinking one is power and one is hooked to the light curcuit

Post some pics of the wiring, connectors, and back of the radio. The radio should have 3 wires with bare ends or a 12V connector of some sort. red (main power), black or green (ground) and maybe orange, blue or yellow (faceplate dimmer). That is it for power input circuits. I'm sure the colors could vary but there should be 3. If you have all of those wires accounted for and still ahve that extra orange, perhaps it's a trigger to turn on a device like a car mounted dvd? The way to tell this is to power up the unit and go through the various modes and see if that wire sees voltage during any of them.

Obviously, all preamp inputs and outputs, audio and video should be RCA connectors, so i doubt it's low voltage in or out.

Do you have the faceplate dimmer circuit already accounted for on the radio?

I will post some pictures today, the refurbishing of radio gave me two separate RCA jacks on rear of radio for mp3 player, then I have hook ups for 4 speakers, one red with fuse for power and a extra orange. Coming from car I have a few greens and blacks for original speakers ,I think.(car has a rear speaker option, i am not going to use) and then I have the red and orange wires that come off same connector. When I check the internet I read the orange from car is for radio light, so I don't know if the radio will have a light or not, at this point. Might have to do as you said trail and error but do not want to blow any thing up.

Some Pictures of wiring, as you can see the red and orange wires are from car, I unplugged them from car, so I guess I just tape off both orange wires, the one from the radio and the other from car, what do you think?

I would be asking the fellow that refurbished it how the light is powered. It should have been the Orange wire. When Gary Tayman http://www.taymanelectrical.com/ did mine, he reused the factory plug, so the radio and light power part plugged back into my car's harness. I don't see why your radio would have a DVD input if it has no screen to diplay video or a wire going out to a video display.

Some stereos have one power circiut (red wire) and the light is powered off of that circuit. They then have a separate wire that is a 'trigger' wire that connects to a low voltage trigger from the car that informs the radio what brightness level the faceplate should be at. You see the difference here vs our cars? In our cars, the dimmer switch decides and limits voltage. In some cars, the stereo limits it.

No way a guy would wire a refurb radio like that, but this is why you need to call him.

in my 68 Plymouth service manual, should be the same for a 68 Dodge/Coronet, the orange wire goes to body wiring, so it's with the dimmer switch on lighting, it looks like anyway... but if the guy that did the refurbishing/rewired it differently & said not to hook it up, I would absolutely clarify that with him...
