    Bumping this thread to add another method of pin extraction. I needed to remove some pins today but couldn't find a suitable tool, so I had to get creative.

    Basically what I figured out is you can take a piece of plastic from some packaging and cut a rectangle, then wrap it around some wire approximately the same diameter as the c101 pins to get it in a roll that is about the right size. You can then insert it around a pin to release the tabs. It took a bit of trimming to get it the right size since you want the roll to be the exact circumfrence of the pin with no overlap ideally. The plastic I used was some stiff packaging from a tube of loctite.


      Heres the tools I used to re pin mine. All the part numbers for the pins and stuff listed on post 1 are what you'll need.

          You need the pin removal tool. either buy or make one. IIRC it's the same tool.

            Would someone mind removing the apostrophe from the title?


              You need to unlock the twist lock pin holder. I used a pick tool. Same thing works for the diag connector. Then you need to make a round pin removal tool. Old antennas or those extendy magnets work great. Just cut it apart.
