valve question?????

hey just wondering if anyone might beable to help me out, i just bought asco valves and on the solonoid theres 3 progs on it, what would the 3 one be for? they didnt seem to come with a chart for wiring or anything.

You only use the tow that are parallel to each other. The third one is connected to one of the others for some reason. But in our application just use the two that are parallel to each other. Ground one, power to the other.

ok thanks, ya i figured it was just two that were used but was unsure of what that 3rd one was all about. sounds good il hook it up like that then, thanks
