I want to modify my Squier Classic Vibe 50s Strat so it has a killswitch on the pickguard. I've got a SPST on-off switch with two wires coming out of it. Would I cut one of the wires attached to a pickup and then solder the two ends of the SPST wires to the split wire? I'm not really sure how to do this or whether or not I have to use a specific kind of switch.
