7-Way Trailer Wiring Recommendation for 2002 Toyota Tundra

Question

Question:

I am looking for a wiring harness to accommodate my brake, tail, turn lights, and eventually a brake controller 7 prong for a 2002 tundra. I have removed the bed and am building a flatbed. I want to use the existing OE factory wiring ends if at all possible.

If you removed all of the wiring of your 2002 Toyota Tundra when you removed the bed you'd want a 7-way kit like the part # 20023 which will wire into the truck's current wiring. Otherwise the 4-way kit part # 118378 plugs into factory wiring to provide a 4-way.

To convert the 4-way then to a 7-way so you can install a brake controller will require the install kit part # ETBC7.

I attached a couple install videos for these kits for you to check out as well.
