    2015 Tundra SR5 Off Road
    Air bags, 45 gallon Fuel tank, Brake controller (P3)
    I have a 2015 Crew Cab Max 5.7 auto. I installed a Tekonsha P3 brake control. The2015 came with a plug in harness but were not factory installed. The 2016 had the oem controller installed. After reading a well regarded publication they stated that if not factory the prom likely would need a reflash to incorporate all the ECU's features such as sway control ( yaw ) and others. Has anyone come across this ? Thanks for any help.
