You will want to connect the Vehicle Wiring Harness # 118343 to both taillight assemblies on your 2002 Mazda Tribute. The wiring harness needs signal from both taillights so the trailer's turn signals will function properly.

The 4-Pole connector provided by the 118343 harness will provide taillight, right turn/stop, and left turn/stop functions for your trailer.

I have attached a help article on trailer wiring for you.
