Man it is harder then you think,I have about 5.
when you scrape(cut) the block make sure you have a sharp exacto knife,and a good Magnifier If you can get part of the terminal to show ,just put a little resin on it and you are good to go.
Some people do the fast Hack,I am not a fan of it my self,It is alright if you are using a Yeti board
Just 3 wires 2 to the block and 1 to the USB solder head for a common,and 2 more if you want ext power.
Just remember it is not as easy as it looks.
If you have any trouble PM me ,I have several parts,Use 30 awg servo wire....Good Luck
They are my favorite camera by far well worth the trouble,I am doing 3 more right now.Get a 1040 Pelican case with a 3/8 lens hole gasket,the lens comes out so you need the extra clearance
If you use a Otter box you will need a snorkel.
STAY AWAY FROM THAT BLUE RIBBON with your solder iron.
