you're in luck. i just installed the same valve on my 70 ss last sunday. my car originally did not have a/c and someone added everything as it should be, less the vacuum valve.
actually, this valve was dropped for the 72' year and was not used, so if you have installed it, it's not correct. but if you want to hook it up, the vacuum line was black with a white tracer. it leads to the bottom vacuum valve on the a/c control panel in the dash. this 3 way valve has one hose that leads up to the top valve, with about 6 or 7 hoses, this white one and one goes to an actuator under the dash.
mine worked perfectly after hookup.
mail me back if you need further help.
