Re: AUX input jack for 67-72 AM radio
Radio comes on as soon as you unplug it, and I did mine in 1 1/2 hours, i found it was a very easy job!!

Re: AUX input jack for 67-72 AM radio
Will this same concept work for a USB port?
and you are correct...I'm not normally allowed near electronics... |

The AUX jack is just an analog +/- connection.

Re: AUX input jack for 67-72 AM radio
Did my mod and thought that I'd mention a few things.
- The directions were very well done. - The resistors allow you to connect both stereo channels to one mono channel without risking damage to the MP3 player. The recommended 2K value can be different, but too large will attenuate the signal and lower the volume. The package size of the resistors doesn't matter as there is very little current. 1/4 watt are easy to work with. They could be incorporated into the wiring if you use larger resistors with leads that are too big to fit into the small terminals on the connector. - There is no way to drive two speakers in stereo with this mod as the radio is mono and only has one amplifier channel. - Someone asked about a 3pin connector. the 5 pin includes a switch that allows you to use am radio or aux input. If you use a 3pin connector, you would have to disconnect the am radio. Simply wire the audio pins of the connector to the blue wire. The resistors should still be used. - The mod MAY work with a non-working radio. it depends upon what is wrong with the radio - meaning the tuning circuit or the amplifier. If you here static but can not receive stations, the mod should work. If I think of anything else, I'll update this post. Thanks again for the detailed instructions. Posted via Mobile Device

Re: AUX input jack for 67-72 AM radio
Just did this mod. So happy I did. Only thing I did different was I cut the blue wire in half and soldered the other wires to them, rather than resoldering to circuit board. Thank you for this write up.

Re: AUX input jack for 67-72 AM radio
So can this be done with an AC Delco radio with stereo capability or no? My 1981 C10 has an AM/FM AC Delco that supposedly came out of a Corvette that fits perfectly into the factory slot. My 68 c10 has an LMC type retro-fit radio that I might want to try also.

Re: AUX input jack for 67-72 AM radio
Finally got around to doing this today. Works pretty good, but the little Radio Shack jack doesn't seem to grab onto the plug very tightly and it can be a little touchy. Once I get it plugged in well, it sounds fine. I does prove that my 43 year old speaker 'aint what it used to be. If I go into the EQ settings on my iPhone and use the Bass Reducer it helps a lot and I'm able to get more volume without it breaking up. The area where I'm currently living has no music stations on AM so this is a great thing to have when I'm out running errands in my truck!

Re: AUX input jack for 67-72 AM radio
This is a very cool mod and should go into the cheap mod thread. Total cost $4.38 plus tax at Radio Shack! I made the mistake of drilling my hole a little far over then had to use a rotary tool to take away some material to get my 3.5 mm (1/8") receptacle inserted. Also, my soldering gun tip was loose which explained why it wouldn't get hot! Once I got that fixed and I plugged my phone into the jack, it worked great! I am amazed that even I could do it! Geezus my radio was filthy inside, so it took longer to clean it all up than it did to do the soldering! BTW, I used liquid electrical tape to protect all exposed areas.

Re: AUX input jack for 67-72 AM radio
Did anyone else's radio die after doing this mod? I'm sure I installed it correctly and it did work fine for awhile, but now my radio is stone dead. The radio started making interference noise, then it worked intermittently (but not well) and then died. I have an extra AM radio I'll dig up and put in my truck, but I think I'll leave well enough alone and won't do this mod again.

It could be something simple too, if you did the mod yourself, open it up and check it out for something obvious |

Re: AUX input jack for 67-72 AM radio
Any thoughts on an Am/fm? The blue wire from the pot on the am/fm goes to a capacitor soldered on the side of the case. The other wire from the pot which is black goes to the circuit board

Here is a shot of the wires coming from the pot

Re: AUX input jack for 67-72 AM radio
Couple of thoughts:
1. A cap soldered to the case sounds like a tone control, rather than volume. These are stacked pots, right? 2. The easiest way to figure this out is with an oscilloscope. I have also used a set of headphones with one side tied to gnd and uses the signal lead to poke around and follow the signal path. You want to find the input side of the volume control. 3. I wish that had an AM/FM to figure this out. :-) Maybe someone else has figured this out.

Thanks for the insight. Not quite sure what the significance stacked pots have but it does look like there is two of them kind of. I will try the headphone idea and report back.

Re: AUX input jack for 67-72 AM radio
I just bought a neat device that adds Bluetooth to an aux input. It works great with no loss in sound quality. I leave mine plugged in all the time and never have to touch it. I bought this because I listen to music through my iphone. The phone has a water proof case and it was a pain to plug into the aux jack.
Seems like you guys adding the plug to the stock radio could add one to the back of the radio somewhere. Then you could hide the Bluetooth adapter and your system would be completely wireless. People would be wondering what AM radio station you are listening to with all the cool music and no commercials. Here's a link to the one I bought. Amazon.com: Rockford Fosgate Universal Bluetooth... |

Re: AUX input jack for 67-72 AM radio
My plan is to add Bluetooth. I bought one of these http://www.ebay.com/itm/141283435836?redirect=mobile and one of these to power it http://www.ebay.com/itm/UN3F-Car-Cha...item43bdb9b07c
I will be able to tuck all this up under the dash to have an invisible Bluetooth system. I already did the aux mod to an am radio and have the cord coming about of the dash is a bit of a pain so the Bluetooth should clean things up nicely.
