Question to Jon or JeriCho....once I get the wires soldered straight to the dock on my 5G, is there a way I can test the dock without the caps? Will I mess up anything? Cause I have a DIY 'normal' ipod dock....
iQEM:
Forget trying to convert your USB cable or Firewire into a diyMod dock. Get the iPod dock from Qables or Ridax. Otherwise you're wasting your time and perfectly good cables. The BGs should be able to fit into the iPod male dock connector that comes with 30 pins. You just have to remove some of the pins and it should fit perfectly well. I'll post pictures later of what I have so far with my dock.
wgr73:
As long as you don't want to damage your headphones, you can test the dock without the caps. If your amp has DC blocking caps at the input, then it'll be alright. If you don't, then before you plug in your headphones into your amp, measure the DC offset by putting the black lead at iPod's ground and the red lead at the right channel of your amp's out. Typically anything under 20mV DC offset is okay, but anything bigger you should beware of. Preferably you don't want any offset. In any case, your caps seem to have arrived, so it shouldn't be a problem. Just try to not damage anything

I wonder if you're doing the measurements properly. It sounds more like you're measuring ground to ground, which would explain why both the "left and right channels" measure directly to the same point. Try it again. Set the multimeter to the ohmmeter function. Hold one lead first to the left channel, and make sure it isn't touching the ground. Then wipe the other lead across the row of inductors. When it reads zero ohms, you have the direct path.
Again, I can't imagine both channels leading to separate pads except that you're actually measuring ground. I figure the proper pads would be on the left side of the iPod, looking at the face of the iPod, or the right side of the image. Man, I wish I had a nano in front of me. Try it, let me know how it goes.

I think I have made some progress. I will update with pictures and my theory on what went wrong soon. =)
Guys, I now have a 5G diyMod!!!! I wired just like jericoh, and was only getting sound out of the left ear...well it was because I had the lineout inductors shorted by accident. I fixed that and all was well! The dock worked on the first try! Heres the dock...
Next, the diyMod...
This thing sounds alot better than my diyNano...it has to be because im using BG caps. The bass is deep, and there is alot more soundstage. I'm listening to it right now with my 595's in my sig. This is crazy good! Once again, thanks to Jon (joneeboi), vvs, and jericoh...all you guys who helped. I hope you like the pics.
Managed to get the caps inside, however the left side of my dock is blocked and there is no clip when I push my interconnect for my amp in except for the right side. Spent really long time experimenting where to fit the caps with my dad.
Here are the results on the nano. I took the tip of a spare ipod dock (from qables) out of its housing, and only left ONE pin to test/trace the signal.
Using the ohmmeter function, I have traced it down to the colored areas in the picture attached below. I found two spots with 0 ohm measurement PER channel. The two magenta (purple) have a direct path to the right channel. The yellow spots for the left channel.
