recently purchased 63 wildcat with air. neither air or heater worked. all vacuum lines under dash were disconnected. was able with help of service manual to hook all up with one exception. according to he manual, the blue line off the 't' on the line coming from the vacuum tank goes to the 'max cool vacuum switch but i can't locate it. does anyone know where it is or where it should be? can't be far since blue line is relatively short.
