We are specifically looking at the passenger side right now because there is more into the wiring bundles than the driver side.
Under the factory heated, but non-powered, passenger seat you have the “always yellow” SRS/airbag connector. ANYTIME you are even considering removing this plug you MUST disconnect the battery ground and wait for 90 seconds per the Toyota factory FSM. This means even if you are removing the seat just to give the carpet a good cleaning, the battery gets disconnected.
To the right is the Load-Cell Array/Seat-belt connector. This is the connector that connects all four load-cells only found on the passenger side with the seat-belt connection info.
Next over is the occupancy sensor computer which basically takes strain calculations from the load-cell array and sends that info to the truck computer thru the seat-belt/occupancy sensor harness.
To the right of that is the Seat Heater Computer. Only OEM supplied factory heated seats will have this little black box.
The next up is the heated seat connector.
To the far left is the Mid-Harness/seat-belt connector. This is simply a connection point for mating two harnesses.
Special thanks to David Schmenk and TruckHouse to making an incredible work of art.
