WEll for the life of me I can't locate the pictures of the stuff, so I'll describe....
Oil Pressure - just a regular auto parts oil pressure gauge. Your tractor is like mine, it does have a oil pressure idiot light, you can tap in where that pressure sensor is. While sitting on the tractor, on the left side of the enighe, near the back above the starter. You will see a 1 1/8" or so hex plug screwed into the block, there will be a single spade connection comming from the center. Just a single wire connected to this. Take this out, get some brass T fittings or something to add the oil pressure line that will run to the gauge. The small pipe thread is standard us 1/8" pipe thread.
For the temp gauge I went with the standard Kubota set up because the sensor is the one for my engine. The gauge and sensor I bought from TractorSmart.com. While sitting on the tractor, on the back right side of the cylinder head, there is a plug where the sensor goes. You remove this plug and screw in the brass sensor. The plug is right next to a head bolt and injector. You should be able to tell which is which. From there you need to tap into a hot wire when the key is on, then the single wire from the sensor to the gauge. The gauge is marked + - S if I recall.
Wait, found the pics. First is the temp sender, you can see the yellow wire and red connector at the back of the head.
