Working similar project...need some help
Have been going through pretty much the same headache as mickstan on this...have a 99 Chevy S10 with the factory Delco head (AM/FM/CD player instead of the tape deck).
Am not ready to shell out the 70+$ for some of these 3rd party hardware solutions, but rather than dig into the guts of my radio, am looking to find out some info on the 9-pin connector on the back that's used to connect with aux inputs. Does anyone have any idea of the pinout for the connector?
Appreciate the help.
Cassette pinouts and how to switch between aux/radio
I did the same thing on my radio (which looks exactly like the picture in the start of the thread). I have a Delco radio with cassette player in my 1993 Saturn. I opened it up and saw the same 5 wire cable from the cassette to the control board.
[FONT=Courier New] orange = right audio channel
white = left audio channel
red = 12v supply to the cassette unit
brown = select tape as input when shorted to +12V (red wire)
red/white = select radio as input when shorted to +12V (red wire)
The red/white wire appears to suck a bit of current, while the brown one doesn't. But If you use a SPDT switch with the red in the center, and brown and red/white on each end, this should let you have a radio/aux in switch.
You need to run a 6th wire for ground. Since the cassette must use the chassis as ground, I don't see a problem with that.
You shouldn't have to cut any wires. I found that it worked fine with the existing cassette circuit connected, although you may want to disconnect it if you aren't using it.
In addition, I found the left/right channel signals from the radio board (top board) to the control board. It is along the 8 wire ribbon cable. Unfortunately, I can't tell you which is pin "1", but the audio is on pins 5 and 6 counting from the back.
may not be worth the trouble
After finishing this project, I'm not sure it was worth it. The audio quality has less "hiss" than using the tape adapter, but the treble is noticebly less and the bass is way too much. I'm guessing that the audio amplifier is designed for tape input and only tape input. I think it is compensating for typical tape frequency response.
Im making a stereo out of one of these to
Hi i am making a stereo system out of a delco radio from a 94 chevy very similer to yours, I was wondering if you could tell or show me where the wires go on the back for power, speakers, clock etc. if not thanks anyway.
