What OEM items go in the blanks

2 of my 3 have wiring, just wondering what goes in them off the factory line.

 

I believe seat heaters and 1 is maybe a blank for whatever you want to do

 

The 2 outside blanks both have wiring clipped into the back, center left is the only empty.

 

I can't find anything for the end ones. Looks like the middle one may have been A-Trac at one point. Lots of people adding aftermarket heated seat controls there though.

 

Yes, that's where my A-Trac button is.

 

I was wondering the same thing!

 

Middle left is A-Trac (TRD Offroad), outer ones are heated seats (Limited).

 

can that lower dash panel be retrofitted into a 2008 with just two cig 12v?

 

It sure can with some disassembly of the centre console and radio. There are a few threads on this.
