What pins in the dock are unused? I think i'm going to go with attaching wires in parallel with the original Line Out and having those wires go to 2 unused pins in the dock. Then I'll make a corresponding 30 pin connector with the Caps in them. I'm still debating whether or not to actually do this. I've never soldered anything so small, and the only thing I have ever done inside an iPod was to replace parts. And even doing that while grounded I still managed to fry an iPod's mainboard. Maybe the next time I open up my iPod to replace a battery or something I'll perform the DiyMod.
This is just slightly confusing. take a look at ipod pinout at pinouts.ru. You'll notice pins 7, 14 and 17 are unmentioned. I used 14 and 17 so they are verified to be unused in my nano but the access was a bit of a pain. a different ipod may have different access. I warn you though, that these pins are VERY small, and pretty tough to handle. I think if you'r capable of it, you should know what to do. The confusing this is the numbering though. the numbering at pinout.ru is INVERSED fram that marked on the board. It's not hard to figure out though. if you're looking at your ipod screen like you normally would, according to pinout.ru, pin number 1 is on the left, when you flip the ipod over and work from the back, it'll be to your right. I suggest you have this covored before tackling anything, and make sure you know what you're doing.
Good luck
For all iPods (AFAIK), pins 1, 2, 15, 16, 29 and 30 are all internally connected, so there isn't a difference between "audio" and "regular" grounds. I prefer to use the grounds other than 1, 2 because it reduces clutter inside the dock and lowers the chance of shorting anything. For the iPhone, you want to connect pin 11 to ground (preferably 15/16 but any will do) in order to get any music from the dock, so you could kill two birds by soldering your "audio" ground wire to the jumper between 11 and 15.

Thanks for the info. So pins 7, 14, and 17 are unused by anything correct?, or are they just unknown? And if I solder the wires onto 14, and 17, it would not affect the original functionality whatsoever (Docking speakers, data transfer etc) right? Thanks again.

I can only speak from my experience, where pins 14 and 17 were unused in a second gen ipod nano. soldering signal lines to them didn't effect any functionality that I knew of and my mod worked perfectly. Although, I did end up melting a bit of my clickwheel ribbon connector, which still worked for a while, then clunked out. with specific precaution, or possibly more space to work with, you may have better luck
Hello again. I have some Caps from an old Portable DVD Player, I don't know if these are any good for an DiyMod. Can you guys tell me if they are adequate?
List of Capacitors:
Brownish "Sammi": 50V 1uF, 16V 10uF, 16V 100uF, 16V 47uF, and a 16V 4.7uF.

Thanks. If the pins are unused then I'm wondering why there are things soldered onto them.
All those capacitors are within spec. Just make sure you have enough for both channels. Find the setup that sounds best and you're set.
Will Caps with a higher uF rating sound better, or is it preference? Because I am sure that I can fit the 10V 100uF Samcons into the iPod casing itself. Also is there a difference in SQ if I use different color Caps, the Black Samcons seem to have more capacitance while keeping the size small, while the brown caps seem to be able to handle a lot of voltage, but very little capacitance.
