Secret wire harness

Hello im brand new to TW.com and wanted to ask. So I was thoroughly cleaning my newly purchased 2006 Tacoma and stumbled across a secret harness that I have no clue what it's for. Do any of you have an idea. It is underneath the small triangular shaped plastic underneath the AC vent directly to the right of the radio console.

 

air bag on off im pretty sure. that's where mine is

 

Ah for key switch styles . thanks coop

 

That's where the air bag key switch is on the access cab. Some trucks don't have a switch there. Can't remember if it's double cab or standard cab. Maybe it's both.

 

The secret is the Yellow loom over the wires. Yellow is the code for the SRS / Airbag System.
