In order to add a 7-way to your 1999 Toyota Tacoma you will need to start with a 4-way. The T-One Vehicle Wiring Harness # 118379 is the most reliable option. This will plug into the connection points behind your tail lights for installation.

Once you have added the 4-way you will be able to add a 7-way using the Universal Installation Kit for Trailer Brake Controller # ETBC7. This kit comes with the adapter, circuit breakers, wiring, and everything else you need to upgrade your connection to a 7-way.

I have attached some installation videos below for your reference.
