THat you actually need an electrical diagram to know which hose opperates which part of the AIR injection valves. The vaccum supply line from the resevior comes into the valve on the oppisite end of where the wire plugs in, the front valve is the EGR valve and is supplied by the same line as the AIR injection valve lines.
