@mawr I don't have appropriately sized spare wire, so I'm using the wire from the cable. It's insulated with super thin epoxy or something, so I have to burn that off the tips, first.
@mawr next is the wiring of the headphone jack! Wiring up for a test first, then solder, then heat shrink tubing to seal it up all nice. ^^
@mawr and then the headphone jack goes in! That was a pain to screw into place. I also drilled and cut into the retention bracket to make enough clearance to fold them up. ^^
Done with part one! On to part 2...
@mawr After taking some time to practice with the female 3.5mm jacks, it's time for part 2.
I'm nervous about this one, wish me luck!
