hot rod air install instructions?

[fredscarryall]

i have a hot rod air stardard elite 53-1000 complete heat/cool/defrost vacuum system in my 1950 suburban that i am installing. i am now to the wiring and vacuum lines and i didnt get instuctions with my kit. i know hot rod air closed a couple years ago and i have looked for hours on the internet trying to find instructions with no luck. alot of people say hot rod air is a knock off of vintage air. the two systems look the same. but the wiring is a totally different color and hot rod air has a third vaccum valve that vintage air doesnt. does anyone have instruction?
