Question:

I am looking for the female end to the electric brake connector of part number HM11143395. I have a 2007 Toyota Tundra and I need to install a 7-way harness. Do you sell the female end of the electric brake connector? Thank you for your time

If your vehicle was equipped with the tow package, the female plugs for the wiring harness # HM11143395 you are looking for will be located on your 2007 Toyota Tundra. I have linked a screen shot from our installation video as well as the video to this page to help you locate them.

If your Tundra did not come with the tow package you will need to hardwire your truck to use a brake controller. The 4-way harness you will need is # C59236 and to adapt your 4-way to the 7-way I recommend the # ETBC7, because it will come with everything you will need including a circuit tester.

For a brake controller, I recommend the Tekonsha P3 # 90195, because of its easy user interface. The P3 is a proportional brake controller which means it senses how the tow vehicle is slowing or stopping and applies the trailer's brakes with the same intensity. It also has a full display screen instead of codes that need deciphering. The Tekonsha P2 # 90885 is like the P3's little brother, it has all the great qualities but doesn't have the display of the P3.

If it did not come with the tow package you will hardwire it in with the included plug when installing the # ETBC7.

I have linked all the above mentioned products to this page as well as a few installation videos and a Help Article on installing brake controllers for your convenience.
