Remove the screw in the power bar tab, after removing the screw separate the grey L shaped cover from the button block under the buttons. There is a little tab you move to the side to separate them.

I cut my servo to length before hand, this servo has been modified to split the common on the servo, I normally split it elsewhere to share for the external power negative and the power/shutter common on the control board.
In this picture:
Red- external power positive
Black- external power negative (which will also be common on the control board)
Orange- power (on/off)
Yellow- shutter
Blue- Fasthack (lens) wire

Now put the servo through the hole in the front of the case and route the wires like I have in the picture. The external power wires go under the ribbons on the bottom of the main board and up through the lens ribbons on the side. The fast hack wire goes under the ribbons on the bottom of the main board and then around to the back of the camera. Power and shutter will go up the front and next to the flash, make sure not to pinch them when putting the front half of the case back on.

Here's where to solder your external power wires, red is positive and black is negative

Here's the power and shutter wires soldered in place. After doing this you can reassemble the button block and grey L shaped housing and screw back in place.



You can now put the front half of the cover back on, I leave the tape over the capacitor contacts. If fasthacking the camera run the fasthack wire in front of the lens and around to the back of the camera. Then remove the white wire from the backboard and solder you fasthack (lens) wire in it's place.
