78 heater info

Hey guys I need some heater info. I did a cab swap and nothing got labeled so I'm pretty much guessing at what goes where. I think I have it all except the blower control switch. The original plug melted and so all the wires were seperated. I have the donors plastic plug but no idea what wire goes in what position.

A diagram would be great! And vacuum line info would help out as well since there is one vacuum switch I don't have a line for. Anyone have info like that? This no heater business isn't cool right now (pun intended)

Also, The heater fan switch was changed during the 1978 model year. The dividing Serial number is CA0001. If you go to a ford dealer(if it still has parts that old) or a parts house, you get the newer style switch.
