i was about to put in my radio in today, after replacing the speaker wires, etc and i went to connect the wires together, and on the radio side, there as like a clear plastic conector with 4 metal plugs on the inside, and what i have on the car now is just the straight up speaker wires hanging out of the radio hole thing in the console. Also there was a single wire (that i assumed to be the ground wire) that doesnt match up to the ground wire thats on the car right now. keep in mind that i didnt change that wire.

what im getting at is that i would appreciate it if somebody would post a picture of what thier 77 radio wiring looks like. thanks.

a multimeter will help you solve all your problems.

i really dont see why people attempt electrical work when they cant simply test wires.
if its an aftermarket radio, the chances that it fitting to the factory loom are almost nil. and in fact, no car i have ever pulled apart has factory wiring behind the radio, especially if they were built in 1977.

perhaps someones photo can help, perhaps it cant, but in the meantime, go get a multimeter and at least measure the voltage in the wires so you have constant 12v, accesories 12v and ground.

if you dont have those, your gonna be in trouble no matter what happens

Sometimes a 12V test light is even better....

Yeah, in an early car with a 3-speaker system, I wouldn't even bother trying to use the stock wiring for the radio. Speaker wires can be done better with new stuff, a new local ground would be beter too, and then the only thing you might want to keep stock would be the basic power wire.

okay well its the stock radio and i want to keep it stock. and, a picture would help becuase i want to know what peices i need to find. i dont need to know what voltage its getting, because i know it works.

I guess something to add to this equation, and to what people are saying, is that by re-doing the wiring you are eliminating chances for either burning out your stock...20some year old radio...or starting an electrical fire. I have met a few idiots who have started fires through their radios by crossing wires, or not knowing which wires go where. As to the multimeter, it will become your best friend. If you are going to start anywhere, DO start by finding the 12v, 12a, and ground.

Even if you know it works, it is nice to know how it works, and if you ever want to change it, then you know what wires to use.
