Air cleaner control help.
Posted: Sun May 19, 2019 1:27 pm
So...iv'e been cobbling an air cleaner assembly by using parts from an 80 bronco (for the base and cover) and bits fron a 90 dakota (the hot air flapper).i would like to very much get rid of this crome "performance" air cleaner i have now...and get cool air to the intake when driving around.and warm when i start it in colder weather.
The hot air from the manifold heat pipe is controlled by a diaphragm...to control that i need a vacuum source that switches off when the engine warms up and on when cold.i'm thinking of re-purposing a cto switch.the switch on the truck now,is a four port blue one...i dont have a part number.good idea or no?
I can test the vacuum,but i dont know which port is the vac supply for the switch...any help?
