Guest johnahays Posted August 27, 2010 Share Posted August 27, 2010 I am in the process of helping a friend with a restoration of a 1972 Olds 442 convertable. Previous owner(s) cut the wires to a factory 8-Track player. There are seven wires coming out of it. Does anyone have info on where theyconnect or a wiring diagram for the radio and tape deck?:confused::confused::confused: Link to comment Share on other sites More sharing options...
Larry Schramm Posted August 27, 2010 Share Posted August 27, 2010 I believe that in that era there would be common for almost all GM cars. If my memory is correct, and you have 7 wires, there would be 4 wires for speakers with one pair of the speakers being blue & yellow, another like a light and dark green. Of the other three one would be 12 volt battery voltage for memory in the radio/clock, another would be ignition normally a pink or pink with a black tracer and finally a ground which would be black. Hope this helps. Link to comment Share on other sites More sharing options...
Guest johnahays Posted August 27, 2010 Share Posted August 27, 2010 Larry, Here is a breakdown of the wires I have--Yellow w/blue stripe, blue w/ black stripe, and black which is grounded to unit combined in a three prong connector-- blue with yellow stripe and yellow (double wire molded together)--dark blue w/white stripe (single) and dark blue w/red stripe (single). I appreciate your help:D John Link to comment Share on other sites More sharing options...
joe_padavano Posted August 27, 2010 Share Posted August 27, 2010 I hate to say this, but if you're really restoring this car, you had better have a factory Chassis Service Manual for it. The wiring for the radio/tape player is in there, in the chapter on Accessories. Was the 8 track player factory installed in this car, or is it being added as part of the "restoration"? If the latter, be aware that the 8 track requires the stereo adapter as well as the radio itself. The stereo in these cars used the amplifier in the stock radio to power one channel and a separate amplifier for the second channel. Of course, "stereo" in 1972 meant one speaker in the dash and one in the package tray! Link to comment Share on other sites More sharing options...
Guest johnahays Posted August 28, 2010 Share Posted August 28, 2010 Joe, The tape deck is a factory installed option on this car. The original radio was removed by a previous owner and, we assume that was when the wiring was cut. Was there a special radio (other than a stock AM type) installed with the tape deck option? You mention a stereo adaptor-- can find no evidence of another item under the dash and looking inside the tape deck it appears to have it's own amplification system. If anyone out there has a service manual with the stereo wiring diagram it would sure help. I do thank you for your help. John Link to comment Share on other sites More sharing options...
