Step 4: Lets Solder!
To attach them to the Ipod is a little more delicate:
-do not use a really hot soldering iron, I used a 20W and it should be plenty
-do not fry your Ipod by touching things other than the now stripped buttons
I found it easiest if I had a little blob of solder already on my wires, this kept me from getting solder all over a very tiny circuit. Attach one of each color wire to either side of its desired button, I tried to keep continuity with the d-pad for the outer buttons and A being play/pause.
Test each button after soldering.
I found it helpful to work from the bottom up on the Ipod
The second picture is horribly out of focus so I apologize. If you can, try and get the main idea of what I did, its not that different to what ryan did in his.
