[VAC] Re: What is it?

Don. Your trailer had an external thermometer. The gauge was mounted in the 
Central control panel. The metal cable for it went through that tubing and 
had a "probe" on the end of it. You should also see some type of bracket that 
held the probe.
Most all of those thermometers failed, and, no satisfactory replacement was 
every found.
Cut the tubing and plug the hole with vulkem.
Then relax.
