The wiring harness 3040-P has only 4 wires with the white one outside of harness for physical ground connection. what is the reason for 5 wires on the truck side? what is the reason the white wire is not part of the harness through the truck?

Helpful Expert Reply:
The fifth wire on the Tundra brake controller connector is for illumination. This is not used on any of the brake controller we carry and when you install the Tekonsha # 3040-P plug-in adapter, the fifth wire is basically ignored.
The 3040-P is confirmed as a fit for your Tundra, but it is designed for Draw-Tite # 5504 and Tekonsha, # 39523, # 90885, # 90195, # TK90160, and # 39510 brake controllers.
If you do not have a brake controller for your Tundra, I recommend the Prodigy P2, part # 90885. This is one of our most popular brake controllers because it is easy to install and operate.
