Step 2Solder the contacts
1) Strip and tin each wire, and cut the uninsulated end of the wire down to about 1mm for the focus and shutter wires, and about 5mm for the ground.
2) The focus wire needs to be soldered to the small metal "leg" of the push switch, labelled "1".
This will require quite a steady hand and possibly use of a magnifying glass.
Once the wire has been soldered, use a multimeter to make sure it is not accidentally shorted to ground, and to confirm that it is grounded only when the button is pressed.
3) Repeat step 2 for the shutter wire, which solders onto the leg labelled "4".
4) Now solder the ground wire to the metal bracket at the corner of the camera.
5) Arrange the two trigger wires so that they will be out of the way of the mode selection knob (i.e. as shown), and use a dab of epoxy glue to hold them in place.
