I disconnected my box that contains my sensors and switchover valve, I have one line coming from the beginning of my exhaust, to get plugged in on one of the two ports on the left side of the box. I cannot find the other male end to go into the female end on the side of the box. Can anyone tell me what I'm missing?

Hanxter7,
Look right above your passenger side headlight for a small wiring harness that is smaller than a pencil in diameter. The wiring harness is right next to the upper cross member that holds the radiator. Look at the wiring harness and find a six inch long two wire pigtail with a plug at the end. If the plug is not plugged in, this is your missing plug.
If this is your plug, don't ask me how long I looked for my missing plug before I found it here.

If you're deleted that other connection is long gone.
