The factory harness to plug in a brake controller wiring harness on your 2007 Toyota Tacoma is located underneath and left of the steering column, taped to another harness near the emergency brake pedal. There will be a 5-pin connector that mates with the one on the adapter, # 3040-P. The harness does include an additional ground (white) wire that will need to be attached to a bare metal surface.
The P2 is a proportional controller that applies the trailer brakes in proportion to how much the vehicle is braking. It can be mounted in a 360 degree range in the direction of travel and works with electric and electric over hydraulic braking systems. I have included a link to the installation details and a link showing an installation on a similar truck.
