One way Vacuum Valve

Hey guys, I have a 1993 corvette and my one way vacuum valve broke, so I got a new one for a few bucks, but I am not sure how to put it back on. The new one I got has 3 openings and it came from the engine. There are 2 wires coming from the side and I am just not sure how to put it back. I know this is somewhat vague but if anyone has had an experience with this I would greatly appreciate some help.

Thanks, Will

Usually, the side with only one port goes to the vacuum source. If you only have 1 vacuum load, cap off the other port.
