since the holder is so narrow, i had to pull back the sleeving on the jack so it would fit all the way in.

thanks everyone for the circuit diagram, looks like i have some more work to do...

so let me get this strait... the caps are used to take out the pop, and the resistor is used to make the headunit to detect. so if i dont care about the pop, and it works, then am i ok?

when i dont have anything plugged in, the circuit is obviously open, so there is no aux option. but when i do plug soemthing in, it is detected... is that all the resistor does? i think i may just leave it the way it is. 15k service is due soon so i will ask the dealer too...
