Well, another day of disappointments.
UPS took FOREVER to get here with my delivery. Not until after 5 PM. Not until it was too late to call mp3yourcar.com and tell them that after their inordinate delay, THEY SHIPPED THE WRONG adapter HARNESS.
This is what they sent me, in addition to the standard harness that connects to the IPod2car adapter:

I have no idea where this is supposed to go, but it was clear that it was not going to fit the three pin female and 4 pin male connectors in my harness under the passenger kick panel.
Looks like it connects to itself, but then the remaining connector has no place to go.

What a drag. I left a message on their machine for a call back in the morning. In the meantime, someone please verify that I'm not going crazy and this thing is in fact, the wrong harness.

I wonder if that harness is for the earlier C5's (no passenger footwell connections) and hooks into the rear of the factory head unit?

Man, so sorry to hear about this.
Aside from the iPod adapter box and iPod cable, you should have a short harness, maybe a foot long (black) referred to as AB-GM10 (not sure if it's actually marked though). One end connects to the iPod adapter box and the other end (big white connector) connects to one end of the COR-HAR.
AB-GM10
Then the other end of the COR-HAR connects to the two port plugs in the passenger footwell.
Here is a shot of my initial test config:

Thanks, man. Upon further investigation, I see that this GMH20TC is indeed for plugging behind the head unit on '97-'02 factory radios, and my car IS an '02, but what does it mean then that I have these other connectors in the footwell? Are those plugged into the back of the HU and this other cable I just pictured above will replace what's plugged in now or otherwise becomes part of that chain, or what?
I'd rather take the easy way out and simply connect right to the footwell connectors, but if this harness will work, I might be willing to pull the center console and remove the HU in order to plug this thing in tomorrow.
Does anyone have the Peripheral harness part number (not GMH20TC, which connects to the HU), that will allow me to go from the COR-HAR directly to the footwell connectors? Wait a minute, now I see that I don't even have a COR-HAR at all!!! That IS what connects to the footwell connectors. ARRRHHGGGHHH!! This whole thing is fubar.

Thanks for bearing with me, music lovers.
Okay, I think I've almost got a handle on what needs to be done, here.
Check out this picture, showing my wiring harnesses and the back of a stock Delco CD unit (I found one on eBay with pictures front and back)

Okay, this much I've figured out. Harness connector "A" plugs into radio socket "A". The harness connector that WAS plugged into radio socket "A" now plugs into new harness "B". So far, so good, right?
What, if anything, do I do with new harness connector "C"? Like socket "D" shown on the radio, "C" is a male connector with pins. So is "D", so obviously there is no connection made between C & D. Do I just disregard "C"? Or do I disconnect the factory harness from radio socket "D" and connect the factory harness to "C"?
I hope my questions are at least making some sense. TIA.

i know this isnt very encouraging. well maybe it can be. It took me a while to figure it out. I had to walk away and when i went back to it i was on my way again. Once you pull everything apart, you will see what you are dealing with. I know you are trying to prepare for what comes up ahead, but its hard when there are so many connectors. Take your time and it will all make sense

Hi DPG, thanks for the encouragement. It's all handled. I did some late night research and found this oddball cable they sent isn't so oddball after all. There is a post in the C5 Audio FAQ that shows how this harness is installed and even answered my question about the mystery connector that in fact, connects to nothing.
After unsuccessful attempts to contact the vendor at mp3yourcar.com twice this morning, and noting that they seem uninterested in returning my call, I decided that the best course of action was to just pull the radio and install what they sent me.
The good news is, all the connections are in, the radio and HVAC unit is back in, and everything works.
I haven't tried it with the engine running yet, but it sounds terrific so far. I see what everyone means about the squirrely behavior of the controls with the head unit, though.
I decided for now to run the cord through the rear lower corner/edge of the cup holder, so that when the I-Pod is plugged in, it will be tilted back and resting against the ash tray compartment door. I successfully cut the slot, and after I take care of some other business, I'm going to put everything back together. I've ordered two Girl In A Box cupholders, so that'll take care of THAT problem.

Congrats....wasnt too bad right. Now you can take that center dash apart in no time. No matter what adapter, it seems that the headunit control with the ipods is quirky. Im just glad that my ipod fit in the ashtray part with the lid closed. I have the last gen ipod, so its a little bit bigger. COngrats and lets see some pics

Thanks, and not sounding too shabby, either!!
My next trick is going to be in figuring out how to get more volume out of the thing. I already have the i-pod max'd.
Looks AWESOME man
Now regarding the volume, the volume on the iPod should have no bearing on the system since you are using the docking connector (line level signals)...your iPod should have a similar volume level as the AM/FM radio or CD player right (I hope
) I'm pretty sure my setup is like this...

not sure about yours but the volume works on the ipod through the dock connector. Im not sure why, but try using one of the equalizer settings on your ipod. I put mine on rock and it made the stock stereo sound good, Just enough bass. I have my volume at about 90% on the ipod. The ipod acts as a small aplifier and you get a nice boost from it.
Also im not sure if this generation of ipod is different from the last, but it can be which is why your volume doesnt affect it. I know that with the last generation, that the volume had a lot of affect on external components when hooked up externally

Thanks for the suggestion about the EQ. Great idea, actually. I do have one question, though. It was my understanding that the I-Pod would power on/off with the head unit. Mine appears to remain on regardless of the state of the radio. Is that the way it's supposed to be?
DPG/JMc,
This volume thing is interesting
I have a 4G iPod/20GB HD (U2 special edition
)
and the volume control on the iPod does not affect the volume level through my stock head unit (I haven't messed with the EQ, it is off so I can't vouch for that).
And Jeff, the power off/on of the iPod is sometimes flaky too
Once in a while when I power off my head unit (or turn off the ignition key), my iPod will remain on too.
I've noticed that when I get into my Vette, if I insert the ignition key, then insert my iPod into my spec.dock, AND finally turn on power at the head unit, the iPod powers up and plays and everything works just fine. And as long as the iPod remains physically connected, subsequent head unit power offs, ignition removals, etc. and the iPod powers off/on as expected.
Try and experiment a little by first hooking up your iPod without inserting the ignition key (the iPod should power up and remain in Pause mode); then insert your ignition key, then power up your head unit, then immediately power off your head unit to see if the iPod shuts off. Mine will remain on most of the time when I follow this sequence...
I can hear relays clicking in the passenger footwell area and sometimes my iPod will remain on even if the head unit is off and the ignition key is removed. Since I don't leave my iPod in my Vette 24/7 this is not a huge issue for me but it is somewhat irritating (even at 200+ bux not completely ready for primetime I guess)

Thanks Larry. I'm beginning to get hip to the idiosyncracies of this thing. Because of the placement, having it power up and down with the head unit is just going to take some patience and practice. Thanks for the tips. I'm almost tempted to re-route it to my locked glovebox and just be done with it, because I like the auto on/off feature. But talk is cheap. I know I'm going to like having the control at my fingertips, so it's going to probably stay right where it is...
