Parking break switch swap reveals leak coming through sensor plug

I switched the parking brake switch and aired everything up. Air is leaking out through the cylinder part up through the plug. When I turned the motor off the HWH level wasn't lit. As it was airing up the alarm bell went off at 90 psi.  but the travel light never lit. It had been working even with the leak before I swapped the break switch.
What part is this cylinder with the plug built in. Is it something I can order from a Napa?. If not can I use a plumbing fitting to plug that hole and hopefully still be able to travel home . Again I appreciate everyone's help and hope I can return the favor someday.

I took a picture if I can figure out how to post it I will. There are three connections to the brake switch. Two air lines and a third round cylinder with a three prong plug on the top. I hear and feel air leaking out through that plug.

The cylinder to the left is the culprit. What is t and where can I get a replacement?

If it has 2 wires on it, It is most likely the low pressure switch for the light . You can maybe plug the hole.

I thought it had 3 wires. I assume it's what you say. I found a brass plug to bypass but if I could get the actual part it'd be better. I also don't know if the bypass will work.

It looks like there is a number on it, have you tried to Google it?

We didn't have internet. We travel to the nearest town where we get a cell. I will try that but in the meantime if someone recognizes the part that'll be great. Also if I need to worry about driving with the plug disabled.
