Attach the ground wire
Next attach the ground wire, which is a small gauge
wire, and in our example we added a black wire. This
wire is soldered to one of the UBS hood solder pads
on the back of the camera near the LCD display.
Figure 7 shows the exact location.
The modification is now complete. You can drill a
small hole in the Tripod connector and run the 3
wires, Power, Shutter, and Ground through this
location, or add any connector you wish. We leave
this design up to the user.
