The Tow Ready Wiring Harness, # 20137, will connect to the factory connectors on the 2003 Toyota Tundra, but the receptacle does not fit in the factory location. This is the only replacement harness that we offer for the 2003 Toyota Tundra. I have included a link to the installation details for you.
