I posted these pictures in the other thread, but they may be hard to find because the post was not originally about a hydraulic thumb. The PC50UU-1 has a boom offset cylinder that is rarely used. I plumbed the lines for the offset cylinder into a 12V two way diverter valves "in" ports. The two outputs of the diverter go to the thumb cylinder and the offset cylinder. A simple toggle switch selects which circuit receives flow. With the switch in the "on" position, the footpedal offsets the boom. With the switch in the default "off" position the footpedal operates the thumb. The pictures show the diverter, the switch and the crossover relief intended to keep the thumb from overpowering the bucket.
