Add an auxiliary (MP3/Ipod) input to your car's stock radio

Step 3 Solder in Aux input jack

Once you have identified the audio pins, find a place to mount the internal jack. Using short pieces of small gauge wire, solder connections from the pins on the stereo to the pins on your panel mount 1/8" audio jack. Be sure to keep the signals correctly matched to the right pins so you don't end up crossing channels or ground.

This should be possible. You should only need to connect 3 wires I dont know why you would need 7. If you look at step 2 it shows the diagram of the changer output you should connect the ground pin to the ground on your radioshack jack and left to left and right to right. as far as getting the stereo tricked to thinking its connected to the changer so you can hear audio thats a whole different story and would be completely different between stereo manufacturers. I want to do this same thing to my Chevy Colorado but only with bluetooth. I dont know how possible this is but I dont feel like plugging in a cable to my phone everytime I get in. My phone is mounted in the GPS dock on the windshield so I plan on running a USB port inside of the head liner above the rearview mirror so I should have no wires showing at all but will be able to charge and hear the phone, music, GPS etc. If anyone else reads this and has any ideas of how to wire a bluetooth adapter to my stereo please let me know. It does have an option to have bluetooth handsfree but mine doesnt have it as far as I know.

I am doing this in a 2002 Nissan Maxima. How are the wires connected to the aux jack? I bought the one from the link to Radio Shack and don't really understand how to connect the wires properly. I found the terminals on my head unit where I will connect the wires, but from everything I have read elsewhere, I will need to connect 7 wires. I understand where to solder these 7 wires on the board, but what do I do with the other ends???

Hi there.
I'm thinking about doing this to my 2002 maxima as well.

Where did you find the pinout diagram for the cd player?

Thanks

Sorry, I wasn't able to get this working right. After I had soldered everything (very poorly) to the head unit, I thought I had it working. I put the disc in the CD player and attempted to play it but it wasn't working. I was pretty depressed and finally gave up and put everything back the way it was. I never found a diagram for the head unit, but I tried to make sense of the labels on the board. I can' t remember exactly what they said but they were labeled and you could figure out what they meant. Let me know if you are successful with this. I usually love messing around with stuff like this but I wasn't able to figure this one out.
