Not quite an “exact” fit
Quality made product, but I wasn’t informed that I’ll need another different wiring harness that plugs into this one. It had the green check saying it fits my truck but in fact it doesn’t . A little disappointed.

Light up the night with the Curt Output 6&4 connector trailer
The Curt Dual-Output 6&4 way connector # 55664 is easy to install and works just fine. I would recommend it to anyone.
