Wires on the back of blank plugs in dash

Hey guys!

First post and I am looking for help already lol

I have a 2012 double cab sport and was wondering what the wires
are for on the blank plugs on the dash where the
aux plug is located. I pulled the plugs to add heated
seat switches and noticed wires on the dummy plugs.
Any help is appreciated.

 

Wire in this picture is the wire in question...





And here is the heated switch controls fitting perfectly...

 

It's easier to have a universal wiring harness then it is to have different ones for different models. So those switches are there for the plugs that are there on other models.

Hope that makes sense

 

It does. I was just wondering what the plugs were for on other models.

 

Do you have after market seat warmers or do they make OEM now in the 12s?

 

Isn't that where the A-Trac button on the 2nd gen 4x4's go?

 

After market Toyota kit.
