The wiring harness (on the left in the back near the hatch) is a wiring for brakes and turn signals. What's it's technical name so i can order a plug?

What is your question?

2005 Chevrolet Venture. There is a wiring harness in the very back, on the left side inside next to the back hatch that controls extra brake lights and turn signals. What is it called so i can order the "male" plug?
