Steve,
Sparks outlined a method that is spelled out in the RC and OI manual and you should check there for complete explanation. You can also make a switch that acts like a pot if you need more than one or two positions. We do it all the time. One thing to add, I don't recommend soldering directly to the pins on the RC or OI. If you need to replace it for some reason it will take forever, and the heat might unsolder the pins on the board or do some other damage. If you need to make a connection, you can buy individual pins or you can cut apart a PWM cable and make splices into the wire ends.
