56327 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Ford Transit-150, 250, 350, HD

Q: How long does it take to install? I do not have any trailer connector or hitch on my 2018 Transit 350.

I took me a little over 2 hours. Start at the drivers side. Tail light is easy to remove. T25 torx, You'll also need to remove the plastic surrounding it only because the wire from the left side is too short for the black box to reach an accessible area. 3 torx, same size, and 2 of those push button pia's. Then a little bit of jiggling to get it around the hinge. I did not disconnect the backup warning sensor on that piece, I just set it on the bumper. Run the green wire to the other side BEFORE you mount the little black box. I had just enough room with the wires a little tight on both sides to put it back together. The stretched wires will dictate where the little black box can be bolted. I used 2 lath screws, one for the ground and one for the box. You could try just one, but I wanted to insure a good ground. I spliced the power wire on the black box wire and ran the wire through an old air hose I had laying around, just for grins. Run it up to the front along with all the other junk going that way and I had enough wire to go to the drivers side and loop to the rearmost terminal on the power box, accessible by popping off the cover that has the red + cover. Splice in the fuse, then the connector. After you are all done, then install the fuse. I recommend looking at utube for better visuals. You do not have to take off the plastic below the taillight on the passenger side. There is enough room to fish it up if you remove one screw and use a screwdriver to get you enough room. This would have been so much easier if Curt didn't cheap out on the wire length for the two tail lights. The one that etrailer sells costs more, but may be worth it if their wires are a few inches longer. I noticed that video shows a extra foot or so of green wiring. I haven't tested it yet as I have a tester coming in the mail and I don't want to move it off the lift until I'm sure it works. A lift makes it easier if you're 70 and it's a hunnert degrees out.

Q: Says it fits my 2016 transit 350hd but then says single rear wheel only. 350hd is dually. Will this work?

Probably not. The plugs that go into to turn signals may be different or some small stupid crap like that, I would call a local parts store get a reference number and come back to Amazon and buy what I need.

Q: What gauge is the black power wire in the kit?

the wire is not marked , but it looks like a # 14
