Yet Another Air-Ride Question; Valve Set Up

[michael bustamante]

Ok heres my question Im setting up my 67 half ton with front and rear air bags, dominator 2600 (thanks suicide doors) mow I dont want side to side or individual lift/drop. I want to raise and lower the front 2 bags equally and the same with the rear, and maybe do a pancake drop (all 4s) so would I use only 4 valves and use "t" fittings to equalize the air between the 2 bags in the rear and another "T" fitting to do the same to the front or am I better off setting up each bag individually? Also does that mean I need 2 switches and a dual needle guage?
your help is appreciated guys. thank you
oh: and any diagrams would be great!!
