Tilt column wiper switch ?
 

Ok guys, my first post here and I need some help. I recently installed a tilt column from a '91 S-10 into my '65 C-10. I've got all the mechanicals sorted out. I want to use the wiper switch that's on the column, with the '65 wiper motor. I can't figure out how to wire these together. I know the '65's switch uses ground to complete the circuit, but don't know how the S-10 switch works. BTW, the motor is the 2 speed model with washer. The S-10 switch has 3 wires. Anyone here done something like this before ? Any insight into this conversion would be greatly appreciated !!!
