What is this?

I tried to see the pics but couldnt see them because they are very dark. Is there anything we can do to lighten them?

I tried using the flash, but it made it all white.

Here is the album with the added pictures.

It looks like a 12v receptacle but there are different sizes of them hard to tell what size it is…

There are three sizes…

6-volt cigar lighter receptacle and plug
Receptacle inside diameter: 21.34 - 21.46 mm (median 21.4 mm)
Plug body diameter: 21.08 - 21.23 mm (median 21.155 mm)

12-volt cigar lighter receptacle and plug, size A
Receptacle inside diameter: 20.93 - 21.01 mm (median 20.97 mm)
Plug body diameter: 20.73 - 20.88 mm (median 20.805 mm)
Most often used in American automobiles.

12-volt cigar lighter receptacle and plug, size B
Receptacle inside diameter: 21.41 - 21.51 mm (median 21.455 mm)
Plug body diameter: 21.13 - 21.33 mm (median 21.18 mm)
Most often used in European automobiles, and sometimes as a second socket in American automobiles expressly for DC power connections.

Looks like a 12 volt port with a voltage gauge above it.


Edited to change the text from voltage regulator to voltage gauge.

What is the gauge for?

So, I should be safe to plug into it and use it like I do my power outlet in the truck?

Get a multimeter and verify that it actually is a 12 volt connection. You should see 12.2 - 12.6 volts if on battery only or around 13.6 volts if your TT is plugged into electrical power.

Thank you, will do that.

The voltage gauge is handy, hopefully it is wired directly to your battery. My 1971 Travelaire had a voltage gauge.
