That should be a series 3 hydraulic. It will work any cylinder without the wires hooked up, and the hydra-lectric cylinder will work with any tractor without the wires. The wires are for adjusting the depth stop collar, and for kicking the lever out when the cylinder reaches the end of stroke or hits the depth stop collar. With out the wires hooked up, the lever/remote will only stay on as long as you hold it, which is fine. 

When this system is working like it is supposed to, it is very nice.
