well, it worked
the switch is small and out of the way
It's hooked up via an RCA jack mounted on the 4 slot's shell. This way, I can mount the same rca setup on my pgm system and put that in there and use the same switch just by unplugging it from one system and hooking it up to another. I am tired, so the pgm will have to wait until the morning.
I threaded the two wires from the rca jack through the small hole for that white thing on the side of the motherboard and then through the hole that goes through the side of the motherboard's controller port. The hole comes out about an inch from the two spots on the 8th dip.
