In the diagram the HAVAC and RESIVOIR don’t appear to be mounted to the firewall that’s why im confused…
The drawing is a schematic. It shows the relationship of each part to each other, but not exactly how they are mounted in the car.
Dude, I can't tell you exactly how to do it without being there. You want a vac source going thru the check valve, then to 4 places.
1. HVAC (firewall)
2. TAD solenoid
3. TAB solenoid
4. vac resevoir (fenderwell)
Before the check valve, a line of vac source should go to the EGR vac regulator.
