Where would be the best place to ground it?

And final question before I try to gather all my stuff so it arrives right after my exams, I remove the things labeled "Z" before soldering wires to them, or somehow solder the wires to the sides (there was a bit of discussion I read about this, but to do with the similar, larger yellow ones, so I'll ask again)? I've seen people remove other caps and inductors, and other components when using a line out dock or the headphone jack, this isn't necessary as I bypass them right? I plan to keep line out port and headphone jack functionality perfect (insofar as it does not degrade the quality on my new line out wires)

Cheers.

Also, if somebody could help me get the blackgates to Australia, please PM me
Since your goal seems to be to maintain all the original functionality and add a cleaner line out, you don't want to remove those capacitors.

The diagram looks fine other then I can't confirm the locations you're attaching to. I don't have a 4G ipod.

Hm thanks. This is what I'm going to do:
I'm attaching the wires to C53 and C54 after removing the "Z" labeled component soldered on the stock iPod nano. I'll drill a hole in the side of the nano and feed these two wires through, and a wire for the ground which I am yet to find. Of the three wires coming out the side of the iPod, the L and R channel will go into the positive ends of the blackgate caps, while the negative ends and the ground will be soldered to a miniplug to be used with an amplifier.

Now I just have to wait for components

I think removing those capacitors will disable the docks regular line out.

What you could do, bobby, is send the wires right to the dock. It's pretty much the same as the mini 2G, I theorize. Solder the wire to the inductors and caps around where the mini 2G has it. Check for continuity (zero Ohms between two points) using your handy dandy line out dock and DMM and just poke around near that row of inductors and capacitors. I'm not exactly sure which one it is, but you can easily check once you have yours open. I don't know where ruZZ.il sent his wires, but you're free to send yours wherever you please. That's one of the beauties of the diyMod.

If you need further help, we're always here.

I withdrew my sale of the iPod touch. I am not giving up on it so quickly. I emailed iFixit about a guide for opening the touch, and they said they're working on a method that doesn't require special tools, ie. the metal spudger, but just the regular Joe Blow pry tools that we've all come to know and love. He didn't give me a timeline or even an estimate, so I will just keep chugging away at it on my own until they come up with a frighteningly simple method. I saw a replacement front bezel for the iPod touch on eBay for 20 USD + shipping, so I'm not as scared as before about having to crack it open if need be. Okay, maybe I still am, but not as much as before. Then there are the iPhones and the nano 2Gs and classics and Zunes and nano 3Gs I eventually will come to get to know. *sigh*

Help is much appreciated.

Does the "higher" reading of the "south end" mean that that is where I should solder my wire to for the mod? I feel pretty confident that it is, but would like to double check.. Thanks!
I just want to close this case, as it had always been an open one for me. From early in my head-fi career, I learned of the iMod and its 4G-only policy. I decided then that I wanted to buy an iPod photo and get it iModded. That dream never came to fruition because of funds and my discovery that the 5.5G iPod rocked so hard. So through this whole diyMod adventure, I've had almost all of the iPods featured except for a couple, the mini 1G and the 4G photo. That's why you may notice that the 4G photo section is very sparse.

To my good fortune, a co-worker shared that he had a broken iPod photo that he allowed me to fix. I got to work immediately upon arriving home, and I can finally verify that the image supplied to us by vvs_75 with the location of the lineout pins is correct. Indeed, the DMM shows zero Ohms resistance between the chip and the resistors. It's been a long and arduous process, but it's finally paid off.

I can finally rest at ease now.

So BrinNutz, if you haven't tried it still, diyMod your photo using those resistor locations, which are indeed correct.

I'm curious about that iMod AND the Ipod Photo. How does the 4th gen photo using the 5.5gen caps in the connector sound in comparison to the "OG" way (caps connected internally to the HP jack)? Any gain in SQ or is it exactly the same, just more "versatile"?

Sweet, so all my digging around the net did pay off!!!

If I ever get some solder and a decent gun, I'll finish it.

I've now got some wire, caps, and a bigger hard drive, but I think I need a bigger back, because of the hard drive. Anyone know where to get a different back?
