Hello all - first time posting.
I have an old Radio Shack/Realistic AM/FM Cassette Stereo, model number 12-1930A that I can't find the user manual/documentation it came with. It's been sitting around for a LONG time and I want to hook it up on my workbench to see if it still works. However, the wiring on it is confusing me and without the documentation, I can't tell what is what. I think I have 2 red "power" wires so I don't know if one is input, one is output or both are input, etc.   Plus I need to determine which are the positive/negative speakers, left/right, front/back.
I'm hoping to figure it out so I can install it into my 1977 Oldsmobile Cutlass Supreme I'm working on.
If anyone A) knows how to distinguish all the wires, B) knows of a website that HAS the wiring color coding/identification, or C) can scan a copy of an old user manual/documentation and send me a PDF, I'd GREATLY appreciate it.

List all of the wire colors. List colors of stripes on the wires as well.

It's not free, but I was able to locate a service manual, here.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

That's the old 5-pin output connectors on that, isn't it? Here is a "reproduction" of the manual. The colors are the same, the catalog number isn't.
Gray or brown is right +
White or green is left +
Black wires are ground for system and speakers.
Does the wiring plug look anything like what you see in the background of this booster? Realistic AM/FM Cassette 12-1930A Manual -- posted image.

Thanks all for info! I haven't had time to go back downstairs to my workbench to map out the wiring that "i am an idiot" inquired about, but I will take some pictures and try to upload them as soon as I can. I have also printed out the instructions that "haemphyst" linked to so I'll see if they match.
Have commitments this week, hard to get time to fiddle-about with the radio.
