On your 2009 Toyota Tacoma the factory wiring harness has a green wire that is used for illumination. So, you do not need to use the green wire when installing your Draw-Tite Brake Controller, # 5504.

The wire colors on your factory harness are the black (12v power), the red (trailer brakes), the white with black tracer (ground) and the green with yellow tracer (stoplight).

The black wire on the factory harness goes to the black wire on the brake controller.
The red wire on the factory harness goes to the blue on the brake controller.
The white with black tracer wire goes to the white wire on the brake controller.
The green with yellow tracer wire goes to the red wire on the brake controller.

Vehicle manufacturers change wiring configurations regularly, so use a circuit tester to verify all connections.
