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.

@Kim I've attached an installation video of this adapter being installed on a 2012 Tacoma that you can check out to see where we found the OEM plug. Unfortunately, at this point in time I'm not able to add an image into our comment section, but the video will help you out!
