folks, I'm reading through this thread before installing an AUX input in my 2000 FRC with 12 CD Changer and I guess I'm having some trouble following the directions.
I would like to install AUX but really would rather not take apart the radio head unit (factory) to splice in there. So I'd much prefer to tap into the unused 12 CD Changer wires.
The little bluetooth AUX unit that I'll be using came with an RCA cable which is a 1/8" Male headphone jack on one end, and on the other end, a separate red and white pigtail (RCA connectors). I have no problem snipping off the RCA red and white connectors and soldering to the appropriate wires on the CD changer harness, I just am unsure which ones would go where. It also came with a male to male headphone cable (would normally plug into a female AUX port on one end and into your phone on the other).
Can anyone offer some advice?
Forgot to mention that I don't care for using the 12CD changer. Never plan on putting CDs in it, but I understand that the car needs to see the CD changer in order to listen to the AUX input and play it.
I did buy the Radio shack 5 pin female aux port as shown here

Just remember that you need to have a CD playing in the changer at all times in order for this to work. I would suggest burning an audio CD with as many songs on it as you can fit, then leave just that one CD in the changer.

When I did this I had no intention of listening to CDs myself. However since the CD changer has to be loaded with CDs anyways I have on occasion ended up listening to them (like when Glen Fry died and one of the CDs I had in there was of the Eagles) The way I look at it why not keep the functionality of it anyways...........you never know when it might come in handy...............just my .02

If you're NEVER going to actually listed to the changer, just find the 4-pin connector mentioned HERE, snip off the wires on the radio side, and connect the proper left/right/common wires from the new BT gizmo output.

Which one is it, and which pins connect to which wires on the snipped 4 wire connector on the radio side of the harness?

EDIT: found this link detailing installing in an S10. Is it correct?

makes sense, I don't mind keeping it, the extra 5 lbs is not hurting anything.
I guess my confusion is coming from whether I need Radioshack part number 275-214 (the relay with many pins), or Radio Shack phone jack 274-0246 (with 5 pins).

(from post 32)
I always thought the tip was LH, middle was RH, and base was Common. If that's what it is and I'm reading the print properly:
1 - connect both commons (radio and changer sides)
2 - radio side of RH signal
3 - changer side of RH signal
4 - changer side of LH signal
5 - radio side of LH signal
That would leave the common connected, let the changer signal pass through the 'at rest' plug, then connect the proper signals to radio only when you pushed in an aux source and the pointed pins were separated from the changer signals.

Cut all 4 wires that go to the 4-pin plug.
For whatever source you're connecting to the car end of the cut wires, attach left signal to brown/white, right signal to green/white, and common wire to black/white. Don't connect anything to the drain wire on the car side of your cut. Make sure the black/white and drain wire are cut, the ONLY wires still connected to the changer should be the three in the other plug.
Your new source should have 3 wires. If it's a spliced headphone cable I believe the tip is LH, small center is RH, and base is common.

sure is!
So i pulled the panel and cut the connector, and after thinking about how I wanted to route the radio shack connector, I sat down at the kitchen table and soldered wires to the 5 pins using bits of my old GM truck harness from my swap. small scale soldering is not my strong point but I got it done.
Using your guys' diagrams I made temporary connections to everything (left the bare shield wires disconnected from anything - is that ok?), stuck a CD in the changer, crossed my fingers, reconnected the battery, and let her rip

SUCCESS! Using a 3.5mm to 3.5mm I was able to get my phone to play music and it sounded great. Figured I'd take it one step further, and plugged in my Miccus Mini Bluetooth adapter, which is a tiny portable unit that takes a bluetooth audio signal (like from your smartphone) and converts it to audio output through a 3.5mm jack. After making sure it was paired properly, that worked perfectly as well! So now I have wireless bluetooth AUX audio through my smartphone, which will be great this summer on those long road trips.
Now I need to clean up this mess, solder and heatshrink everything, and run the aux port into the center cubby where the bluetooth module will be housed.

Thanks again for your help guys!

the one under the radio, or the one between the seats behind the shifter/traction button? I planned on leaving it in the middle cubby between the seats since I have a charging port there, I don't think it'll be an issue.
