Solved: Aux input for my stock radio! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

marc54 · 11-03-2011, 07:39 PM

I really wanted to keep the stock look of my dash, and dont like the placement of an aftermarket radio. And all I wanted extra was to be able play my Ipod thru the stock radio. Didn't like the available options nor even knew if they would work on my old radio. So I got out my breadboard...

I took out the tape deck and unplugged the whole harness. The wire diagram is stamped on the case of the control module. The ones we're after are,

2- L Audio
3- R Audio
4- Audio Common (ground)
5- 12v
6- Tape on (signal that tells the radio that a tape is playing)

So you're going to solder in an 1/8 inch stereo jack on the 3 audio wires and a spst toggle switch between 5 and 6. In normal tape playing, T-ON is a 5vdc logic level but the control unit appears to be only looking for a signal on that wire so the 12v works.

Easy as that. (do this at your own risk...)

I took everything out of the tape deck and lined it with fabric and put the shell back in the dash.

very nice mod

much better way and be able to keep the tape deck would've been a speaker selctor switch (radio shack) you can also do this with older aftermarket radios that have a c/d changer plug..
or go the real easy way and use the older walkman catt tabe adapter that plays through the tabe decks head.. and yes they still make them and market them for the i pods

Thanks everyone. Didn't really want to keep the tape deck around, let alone not knowing if it even worked. And this mod only costed $6 at Radio Shack.
