Where Does Curt Trailer Wiring Harness Install on a 2000 Toyota Tundra

Question

Question:

I have a 2000 Toyota Tundra with an existing trailer wiring connection that was on the truck when I bought it new from factory. The Curt 55367 does not match the existing connection under the rear of the truck close to the rear bumper. There is no blank connection as illustrated in the instructions. As seen in the attached photo the connector tees off the tail light harness. The lighter colored connector to the top-right connects directly to the 4-flat. Suggestions? Thanks

It looks like the connector you need is actually already plugged into something which I have pointed out in the picture you sent. The empty plugs on the right side do not seem to match the connector on the Curt wiring harness # C55367 for the 2000 Toyota Tundra. Or, if you can plug it into that lighter connector in the upper right and everything works then you are good to go.
