Vacuum tube diagram

[Snowy]

Hi, Does anyone have a good clear diagram for the vacuum tubes for a 73 455? I have a parts manual but the drawings are horrible and I cant really read them. I mostly concerned about the lines coming off of the 3 port vacuum switch mounted next to the thermostat housing opposite the temp sending unit. I purchased an aftermarket vacuum switch and its a little different in appearance. I didnt know if it mattered which line connected to which port.

Thanks

Mark
