Car Forum / Oldsmobile Cars / May 2005Need wiring pinout for 1972 cutlass am/fm - stereo
Hi all, I've got a AM/FM - Stereo radio from an old 1972 cutlass I used to own. The part # is 23AFM. I'd like to get the wiring pinout to see if it actually works. There is one 3-pin connector and a single blue wire with a connector which comes out the side. Any help out there? Thanks Dave Can you make out any letters on the connectors? My 1972 Pontiac manual shows a lot of radio connections that are probably similar to your machine. Power will be on terminal C Dial lighting lamp will be on terminal B Front speaker goes to terminal u (its other terminal is grounded) Rear speaker wires on terminals v and x Radio chassis is the ground return > Hi all, > [quoted text clipped - 8 lines] > > Dave Silver, Thanks for the info, but i believe the pinouts that you gave me are for the mono radio. The one connector with three terminals, one is labeled GND(left) the other is labled spkr(center) and the other label is gone(right). There is a single blue wire coming out from the side of the radio. Check your other wiring diagrams for this possible combination. I really don't want to blow up the thing since it looks like it is in good original shape. Cheers Dave > Can you make out any letters on the connectors?

Tks Dave > Can you make out any letters on the connectors? My 1972 Pontiac manual > shows a lot of radio connections that are probably similar to your machine. [quoted text clipped - 17 lines] >> >>Dave Took another look at my manual. There are no codes like the one you provided for reference. Just a written description for each radio installation. The pinout I gave you was for the "stereo radio or monaural radio with rear seat speaker." It was for the F series Pontiacs. The drawing for the A and G series radio is virtually identical. None of the available installations for any series shows a single wire leaving the radio. It's hard to believe that Pontiac and Olds would be very different in this area of the vehicles. Any chance that your radio came from a different year car? > Silver, > Check for this pontiac part number [quoted text clipped - 28 lines] >>> >>>Dave Found a set of AC Delco Schematics for 1972 radios. There is a diagram for an Olds F85 that shows a hookup similar to the one you describe. The three pin connector carries power for the radio, output to the front speaker, and ground. There is a separate blue wire with its own connector that goes to the rear speaker. Evidently stereo back then meant separate audio signals to a front and rear speaker layout, not left and right. > Took another look at my manual.

That explanation matches the description on the knobs on the radio. Just a front/back fader. Interesting that the rear deck has factory cutouts for the speakers. Thanks again Dave > Found a set of AC Delco Schematics for 1972 radios. There is a diagram for > an Olds F85 that shows a hookup similar to the one you describe.
