i have a hot rod air stardard elite 53-1000 3 vent with heat/cool/defrost vacuum system and i didnt get instructions. hot rod air closed a couple years ago and the i have spent hours looking on the internet with no luck. i know that vintage air and hot rod air are the same basic design. but the big difference is the wires are a totally different color and hot rod air has a third vacuum valve that vintage air doesnt. does anyone have instructions.mainly the wiring and vacuum part.
