sorry about the blur
When I spliced in the switch, the psone wire was extremly thin - after i screwed it up i decided to feed the switch wire directly into the white plastic connecter to the psone power jack, I dont recommend you do that... (red wire as shown below)
when splicing in the switch, remember to only cut one wire on the psone, and only splice the switch onto the one wire, if you combine both sides of the psone power wires, youll blow the lcd and might even blow the electrical switches in your house....
hope this helps
