Recommended Wiring Harness For a 2010 Toyota Tacoma


What trailer wiring harness do i need for a 2010 Toyota Tacoma with rear LED tail lights.

It sounds like you need a 4-pole flat for the 2010 Toyota Tacoma to illuminate the trailer lights. For that I recommend T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # 118496 which has a converter so it is compatible with your LED lights. Tekonsha is a reliable brand that is known to last a bit longer compared to the other brands especially the converters. I have attached an installation video for your reference.

If you need a 7-Way on the Tacoma and it did not come with a factory 7-Way and your trailer has brakes, I recommend to use the 4-pole I recommended with part # ETBC7. This comes with all of the necessary parts to hardwire a 7-way plug on the vehicle. The 4-pole connector would plug into the pigtail coming off the plug in the diagram. I have attached a wiring for your reference as well.

Since you plan on doing some towing you may consider the etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag. If you are not sure how much rise/drop you may need in a ball mount to tow your trailer level, I recommend to take a look at the helpful article I have attached about how to figure the amount of rise or drop you may need.
