Im trying to find the vacuum diagrams for a 04 ranger 4.0L manual 4x4 didnt see them on here or that BBB industries website unless 99 is the same i wasnt sure. But any way if anyone has them please post thanks
 
I don't have the actual diagrams, but it's a pretty simple system. It only has the can, the heater shut off, the fuel pressure regulator, brake booster, EGR, and HVAC.

Everything important but the EGR is hooked straight to manifold vacuum, the EGR goes through a solenoid switch first. The heater valve isn't important and can be left out of the system all together.
