Have a 68 GTO the genius before me pulled all the vacuum hoses out for the heat A/C control. So im going to have to hook them up one by one with out plug. I have no idea which each port should go to. I have 6 ports and found a schmatic here that shows the routings but my switch is numberd and different than schematic or ate least same numbers just differant locations on switch. If anyone done it this way or knows how the system operates would be appreciated.
