We just purchased a 2016 Wrangler, our first toad.
I'm pretty handy with a wrench so I did all the installs myself, took about 18 hours over four evenings. Everything works properly, saved 2500 +\- on labor. I know where every connection is, placed 99% of them where I can stand and check connections, fuse, etc.
These are the items I used, I wouldn't change a thing:
Blue Ox baseplate
Blue Ox tow bar with cover
Hopkins toad wiring harness
SMI Stay In Play Duo brake system
7 pin to 6 pin umbilical
Brake light relay
Love the brake system, plug the umbilical in and the brakes are ready to go! Plus if I ever change coaches it all still works, diesel or gas.
I would be happy to answer questions by email or send photos.
FYI: I have just under 2500 in the entire set up, I went with a 10,000 lb tow bar just because. I really liked the Demco tow bar but then I would spend another 150 for the proper ends to attach to the Blue Ox baseplate. And I liked the BO baseplate.
Best of luck,
