I'm going to assume that you are still running the factory belly pump...
Step 1, buy and do a nice job mounting your spool valve (they can come in single, 2, 3, 4, 5, and I think higher if you want) like the picture above. Don't weld it to the light bar, that looks terrible! LOL Check out the hydraulics section at northerntool dot com for spool valves. Be sure to get an open center spool valve.
Also, in the picture above you can see that I have quick-disconnects set up for remotes on implements. If you have a loader or 3-point hitch you could run hoses directly without couplers and leave them hooked up permanently to the valve.
Step 2, get pressure from one of the ports on your belly pump. There are two on the clutch side and one on the brake pedals side. Use the front one if you are taking it from the clutch side as the rear might be set up for delayed lift with cultivators.
Run the pressure line to the "IN" port of your spool valve.
Run the return line from the "OUT" port of the spool valve down to the belly pump drain. I tried the return going in the top (fill) pipe and it just spit oil out constantly.
The last step is to simply tie the belly pump lever back so it pumps through the spool valve all the time. Try not to be as crude as I was...
