Question:

I recently received my order of the C24VV Brake Controller and C51362 Dual Plug. I cannot find where this would plug into. I do see another plug under the steering wheel but this dual plug will not plug into. Do I have the wrong plug or am I just not finding the correct plug?

Expert Reply:

I believe that the photo you sent in is of the OBD-II port on your 2014 Toyota Tundra. This is useful if your vehicle is throwing codes but it is not used for the brake controller.

As long as your Tundra has the factory 7-Way at the rear of the truck then the Wiring Adapter # C51362 is the correct part for you to install the Curt TriFlex Trailer Brake Controller # C51140. Try looking to your left behind the side kick panel next to your emergency brake pedal. I have attached both a photo and an installation video of when we installed a Curt brake controller on a 2012 Tundra that you can use as a reference.

Let me know if you still can't find the connector and I can help you troubleshoot further.

I can't find the brake control adapter plug on my 2014 Toyota Sequoia. If I understand the images above, it is not bigger plug directly under the steering column ~ but smaller plug located to the left. I have a gazillion wires under the kick plate ~ I read in one place it was wrapped in Electrical tape...is there any other distinguishing feature that will help me locate the adapter plug?
