I have a B3350SU and the switch that turns on the 3rd function broke. Does anyone know how to rewire a temporary switch to replace the broken one. I an getting wood for the winter and I can not wait for a new one from Kubota.

Pretty simple any 12v dc switch will work just need a 12v hot to the switch and for the load side 12v to the 3rd function valve. Need one switch for each function (open/close). I used a 3 position marine grade toggle with spring return to center. So push rocker one way it opens push rocker opposite way to close let go and it stops.

So just 12v hot in and doesnt matter what side of the switch you connect to the valve just depending on which lead from the 3rd function you connect to whichever side of the switch will determine if the grapple opens or closes. Or you can get two separate switches like the land-pride kit and have one for open and one for close.

It is most likely a ON-OFF-ON SPDT (three terminals) or DPDT (six terminals) switch. You can google search those terms for some simple wiring diagrams.

If you can post a picture of what you have we can get more specific and help you better.
