Plow ram lines can be plugged into the loader valve ports that control the bucket dump. This is really easy if you have a loader with quick-disconnects. The rams that control the bucket dump should stay in place after being disconnected from the valve, allowing you to set a desired angle before connecting the plow rams. I am referring to single-acting hydraulic rams, these cylinders have one line each, and are used on most snow plows with dual rams.
As a precaution, a pressure relief valve should be plumbed in between the plow rams and the loader valve. This should lessen the chance of damaging the loader or plow if the plow ends snag something.
I should probably also add, for modern loaders with "regen" or "fast dump," you'll need to be very easy on the loader control when tilting the plow side-to-side. Just move the loader stick slightly right or left. If you open that valve too far then "regen" happens and the plow will sort of shudder instead of tilting. What "regen" is doing is filling both cylinders with fluid at the same time, which effectively stops the ram that should be retracting when tilting the plow.
