Realistic AM/FM Cassette 12-1930A Manual

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.~ Mark Garcia

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? 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."

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.~ Mark Garcia
