I have reciently purchased an old Ford skid steer, and I'm wanting to weld up a grapple. While looking through the manuals I found a section that covers aux. Hydrolics. It states this machine has the feature as an option, and if installed, the valve was mounted under the foot pan. Well mine doesn't have this option, but I did get spare valves and drive motors with the purchase. So, would a fella be able to tie into the existing hydro system and "Make" an aux. system similar to what was built at the factory? Where to start? Which system would i have to tie into? Drive, lift, tilt? Also, i would be able to fabricate the lever for action. I wouldn't mind having a foot control.

You must have one valve which is a "power beyond" or can be upgraded to power beyond with a PB sleeve. The PB valve must be the first valve in the system from your hydraulic pump.
Normally the PB valve is the valve that controls the lift and tilt of the loader (which is your main hydraulic pump, not your drives or charge pressure system) and the AUX valve is plumbed into what would be the return line to the reservoir, kinda.
A PB valve has two "out" flow ports. From one the oil comes out of when you are using the PB valve (again usually lift or tilt) and that oil is returned at low pressure to the tank/reservoir.
The other port is where the flow goes out of the PB valve when it is not being used and this oil continues on to your second valve and is under high pressure (at least its hi pressure when you use the second valve) and then is returned to the tank. Remember which ever valve that is down stream (not PB) will not function while using the up stream valve.
There is no reason why you can't install this provided you can find the room to mount it all.
If you have to buy a new valve because the ones you have are not PB capable, you might want to consider a electric over hyd, then you would not need to make a linkage and pedal up or mount the valve where you can get a linkage attached to it, but rather mount it where it is the easiest to plumb it in.
