The rear plug hole on the intake is for the vacuum wiper tube/fitting. If you have wiper vacuum motors, you would plug into there, if electric, you would plug off using a 1/4-18 pipe plug.
If using vacuum, 1/4-18, 90 degrees, inverted flare, for steel tube about 5-1/2 inches long, rest is rubber hose.
