Ported Vaccuum Switches
I have done a lot of looking and I still can't find the specifications for which PVS I need. I can't refer to the old ones because they are melted down. Is there a way I can find the info? LMC Truck has the switches. They say just compare the color code on top. I searched all my pictures and can't find one with that kind of detail. Another problem is that I am replacing my Holley carb with an Edelbrock. I don't know how that is going to affect the entire vaccuum system if at all. My truck specs are in my signature.

Your carb wont change the vacuum supply. You are still running the heater system off of a tap off the intake manifold.
When I got my '83, the heater/AC vacuum line was connected to the PCV valve with a tee! It did work, but was very slow to react to control changes.

Well since our trucks are not that far off can you post a picture showing the two (or is it three) ported vaccuum switches. I'll be assembling the new engine soon and I want those two parts on hand.
