Installing Tekonsha Primus # TK90160 Brake Controller on 2015 Toyota Tundra

Question

Question:

I have a Primus IQ brake controller and require a new wiring harness to fit a 2015 tundra. Can you send me the part number for just the wiring harness? Thanks

If your 2015 Toyota Tundra is equipped with the factory installed 7-way trailer connector (which it should be), it will have the brake controller install connector under the dash. The plug is located behind the panel to the right of the ignition key that contains the Tow/Haul button, as you can see in the photo I've provided for you. You'll need the # 3031-P brake controller wiring harness.
