Some power steering schematics include a generalized power steering diagram, an electrical power steering diagram and power steering wiring schematics for specific models. Power steering schematics show the whole systems or individual parts of the systems, such as the power steering pump.
HowStuffWorks.com shows one type of power steering schematic, the generalized diagram, which depicts the basic connections and elements of most power steering systems, including the pump, pulley, rotary valve and steering gear box. In addition, it shows the internal schematics of the pump and rotary valve. BrakeandFrontEnd.com has a general schematic of connections for an electrical power steering system and an internal schematic of the position sensor. AutoZone.com's schematics depict the pump mounting assembly and pulley system for a 1986 through 1987 Ford Aerostar.
