Aux Input for an Older Delco Radio

Well.....I was getting a bit of help from my 15 year old son....and I'm not really sure what happened. No big deal. It'll just set me back a little. Yes everything was hooked up to the breadboard and being tested in its stock configuration. Then poof! I'll post some pictures of the set-up later.

Ouch! You probably either shorted some wires together, or overloaded a circuit. Was this testing done with the pots in place? My ex once told me I have a perfect face for radio.

No the pots were not in yet. We just wanted to verify that all of our connections worked and the radio functioned as it should with no modifications. Everything was working fine. I'm not sure, but something touched a wire it shouldnt have. woopsie. I got all of this stuff and now the radio crapped out. figures.

From the pictures it looks like you simply connected color to color using the project board. What is the reasoning behind this? The idea is to test the 5 wires while the cassette deck is playing, then simulate this process to create an aux in while removing the cassette deck from the equation altogether. It also appears you've dissassembled the deck. There's no need to do this. Once you've identified and verified the functions of the wires, you'll just plug in the pigtail you cut off the cassette harness, and wire it in.My ex once told me I have a perfect face for radio.

Well I had to take the thing apart to get to the wires!  Its easier to test with it opened-up. And the deck itself is still intact and functioning, it has just been removed to gain access to the internal harness. And yes it is set up color to color. Heck, I had to start somewhere! The board serves as a place to "intercept" the signal from the deck. It functioned just fine, for a minute. We never made it to the next step.....Verifying functions.

Now I understand- you were still testing. You wouldn't have needed to open the factory deck, though.My ex once told me I have a perfect face for radio.

Opening the deck is the only way to get to the wires. If I didnt open it up, how else could I get to them? The wires are inbetween the deck and radio. Its all one unit. Not 2 seperate components. I wish I didn't have to open the thing up!

Okay, I thought they were two seperate components.My ex once told me I have a perfect face for radio.

Well I got tired of waiting for a nice day to go junkyarding a look for a working delco radio. Soooooo...I caved in and bought one with the aux input from the dude on ebay. As soon as I get it, I'll open'er up and see what makes it tick.
