Red wire To cold side lead at stoplight switch. Blue wire Break output to trailer Newer vehicles have a plug in under the drivers side of dash but older ones have to be wired directly.

The connector for the brake controller is under the dashboard on your right close to the driver's foot rest. If you buy the genuine Toyota wiring harness with the connector then it will not take you more than a minute or so to install it as it fits right into the wiring harness that leads away from the brake controller. Make sure that everything is fixed in place and not lose.

There is a wiring harness most everywhere you look on that and any vehicle. Be more specific.
The purpose of the wiring harness is to help keep wires together instead of hanging freely. You can purchase a new wiring harness at any auto repair shop.
The wiring harness can be removed by unplugging all of the wires. The wiring harness is also held in place by several retaining screws. Remove the retaining screws.
The factory wiring harness for the trailers will plug in under the back of the vehicle in the area of the spare tire, the harness plugs into the wiring harness for the tail lights.
It depends on which Harness you are looking for.
