I realize this is a little late to the party but if you have not yet set up for the brake controller, this will be helpful. It would be nice if the RV centers would simply look at the application sheets for p/n's and such so they could recommend the BEST product rather than something absurd such as a wireless controller when you have the wiring installed.
The P3 has a nicer display, and all of the buttons are on the front, while the P2 has a button and thumb wheel on the upper surface near the face. The P2 display is simpler and shows less info. Biggest difference is that the P3 can store boost settings, number of axles, elect or elect/hyd for four different trailers. The P2 doesn't appear to have that capability.
2003-2014 Tundra's use a p/n 3040-P adapter harness for the Tekonsha controllers. The connector is found (according to the Tekonsha application guide), in the LH kick panel area. This is plug and play.
If you bought another brand of controller and needed a harness, a Tekonsha 3040-S harness has a plug to mate to the vehicle and bare wires on the other end to splice to the connector for whatever controller you bought. If you buy a Tekonsha controller, it comes with a universal harness that you discard or don't use if using one of the custom harnesses.
