Here is a picture of the controls from my Chevy '50 COE.

Attached to the under side of the left dash is a piece of angle iron. My PTO is used to drive the hydraulic pump to raise the bed. Both the PTO and valve of the pump are cable operated. The previous owner just bolted the angle iron next to the heater switch, drilled a couple holes through it and mounted the cables. I just cleaned and painted what was there and re-installed. As Cletis noted, some set ups use levers, which end up coming through the floor board. My cables go through the firewall and loop under the cab (remember it is a COE so the cab sits over the engine).
