PSP LED Fader Deluxe Tutorial Question

[limitedEdition]

Sorry if this isn't in the right place but in the tutorials section for the LED Fader Deluxe Tutorial...

"" Make the Fader turn off over Hold
This is a little modification in the wireing. It's only a very little modification, so I think this will go well without pictures.
First, remove the wire that leads from + to PO. Now take your S1 , and solder it to your Hold switch. Your Fader now turn's off when you push the Hold switch down.

""

What exactly does it mean by solder to the hold switch? a picture would be very helpful

Here is a thread with a hold switch used for a trigger mod.
