wiring valves

i need some help, i got tha valves with the 3 prong hook ups on tha back and i cant figure out how to hook these up, i have my ground in tha middle and a power on one side, is this correct? its tha blitzluft valves

most of the time the one on the bottom is an extra gound you need to us the ones side by side make sure you use the same ones for grounds and poss

thnks ill try that now

use the smaller 2 prongs, the one with the |||- lookin sign you dont use, and it doesnt matter which prong gets power and which prong gets ground.

ok it is working now, i tried every other combo there was, and of course tha one i didnt think of was it thanks guys
