vacuum hoses
I've got a 1977 F150 heater vacuum hose question.(though it looks more like the 78 heater assembly in my manual) I've got 5 vacuum hoses, red, blue, yellow, orange and white, under the dash running to the heater plenum. The white is long and goes to the farthest right(passenger side) vacuum servo. But, which servo and which port do the others attach to? One port is plactic and one metal on each servo.
Any one that could tell me or provide a picture or diagram would be greatly appreciated.

See the two vacuum servo/solenoid/actuators in the bottom left of that pic? Each has two hoses. That's the part I don't know the correct position or color for. All four hoses are just dangling on my truck. Do you know which goes to what port?

I found the answer. My shop manual cd finally arrived. It's from classic auto manuals out of tyler Texas. The program is cumbersome, and you have to put the cd in all the time, and it won't print. It does seem to at least have all the info.
