The one behind the glovebox? It's not difficult.
I don't know if I selected the best solution or not, but it's in, it works and a test drive didn't reveal any faults. I tested the red wires going to a few of the harnesses in the center console - I have the entire hump removed for another project - and found a switched 12V lead, I spliced it with a piggyback easy splice and grounded the modulator to a ground lug that I noticed on the passenger side of the hump. There is a foam air duct that goes from the rear seat vent to the center of the dash - I fished the antenna wires up the depressions in the center of that, connected them and put the PCM head unit back in place. Directly behind the gear shifter there is a metal bridge that the center hump mounts to, the space under it is the exact size of the modulator. I removed the bridge, zip tied the modulator to it, bolted it back in, slid the hump in to check for fit and viola, iPhone plays through my new favorite station, 87.9. I haven't decided where to place the switch or iPod cable yet - but all signs point to the lower compartment in the console.
Thanks for the heads up. The iPod thing I'm using (iSimple IS77) has a toggle switch for power already. But the danger would be leaving it turned on when connected to a constant 12V. It seems like running a wire across to one of the fuse boxes might be the best way to go.
I have a PCM 2.0 and I hadn't considered tapping into the radio's power circuit, that is diabolically clever. Any hints as to where would I find a manual that includes a wiring diagram for such a thing?
I did some searching and I found a few leads but I didn't find a consensus. I want to add an iSimple FM modulator to my 2004 S. I already removed the console and radio to connect everything up and modify the console to accept the unit's switch but I don't have any firm ideas where to get power from. There are fuze boxes on both sides, of course and the cigarette lighter power outlets as well, so I am sure I can come up with something. But, really, what is the best practice in this case?

j3w replied to scott_fx's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Thanks for this! Adding an iPod FM interface this weekend...
j3w replied to gaoo's topic in 9PA, 9PA1 (Cayenne, Cayenne S, Cayenne Turbo, Cayenne Turbo S)Looks a LOT like the switch to an iSimple FM modulator.
Bump for an answer...
Funny -- I'm in exactly the same boat. Except for one thing: driveshaft, coolant pipes and front diff all went within the last two weeks. I have a 2004 S that I loved dearly before it ate $5000 on me. I just turned over to 130,000 miles. From 80-now I had few problems aside from regular wear and tear items. So from that I'd say you might easily have 30,000 trouble free miles ahead of you.
Just rephrased my search and found a thread. Sorry for the clutter.
I have been trying to figure this out for a while now, to no avail. Perhaps someone here can help? When I am coming to a stop in my 2004 S, in the last 10 feet or so as I come to a complete stop the engine idle falls to 400 RPM, for a second or so. The car shudders, the idle picks up and everything is fine. I have a foot on the brake and am slowing like at a traffic light or something. Has anyone noticed this?
