what switch did I forget?

Took apart driver side dash. Going back together I have a single plug loose, and I don't remember what it goes to. So, what did I forget?



ETA: solved. TPMS reset.

 

Turn on your dash lights and see what doesn’t light up

 

It could be an unused plug. Was previously a Toyota mechanic. I’ll still amazed the number of people who will take a dash apart and not mark the connectors.

 

I'm thinking it was unused. There were no lines on it from being inserted, or dirt line, etc.
All other plugs were accounted for, everything I've tried works. But you dont know what you don't know

 

Are there any blanks in the dash that have a receptacle for it. The switch blanks.

 

Nope, I had only one blank with wires, top section, right side, for the inverter.

 

Solved. TPMS reset. Evidently I didnt look very closely at the lower panel

 

Thanks for letting us know.

I remember pushing that button so many time I thought it didn’t work.
Then I figured out there was a TPMS sensor in the spare.
I don’t believe the later trucks had them, but my does.

Now the light just stays on, the battery in 1 or more is dead.
