Wired like it said on 2014 ultra limited did not get any of the 4 wires not the trailer end to work?
Warren on Mar 25, 2017
BEST ANSWER: test light time!
what is it on the trailer that determines if I need a 4 pin or 5 pin plug from the bike? I have a single/left/right LED tail lights. No accessories.
paul s on Sep 13, 2018
BEST ANSWER: If your trailer has separate brake & turn signal lights OR combination brake/turn lights AND axle brakes, you will need a 5 wire set up. Otherwise, 4 wire setup is used for most trailers with combination brake/turn signal lights and no axle brakes.

4 wire is white=ground, brown=tail/running lights, yellow=left turn & brake light, green=right turn & brake
5 wire is white=ground, brown=tail/running lights, yellow=left turn or combo, green=right turn or combo, blue= separate brake lights or axle brakes
I have this . When I put my brake on all my lights come on and it blows the fuse.what's wrong??/
Gerry D on May 5, 2018
BEST ANSWER: I installed mine just like the instructions said. I ran the wiring in the gap between the fender and strut on the right side and zip-tied it in the most direct route to the hitch keeping it away from the exhaust as much as possible. Never had an issue. The only thing that I do different is that when I'm not using the hitch to haul a trailer , I pull the fuse .
I was told this will fit my 2018 Street Glide?

Excellent but room for improvement
The wiring harness plugs in directly into the factory harness perfectly. The relay module is sealed with epoxy to make it weather proof and is small enough to stick in front of the battery box. You can easily unplug the harness that runs to the trailer at the relay block for when you are not towing the trailer. My only criticism is that the fuse block gets connected with cheep crimp connectors. I soldered the fuse block to the red power wire and use heat shrink tubing to make that connection more weather proof. Other than that, it's a great product.

Works for tour pack lighting too!
I used this wiring kit to connect lights to an old style tour pack I installed on my bike. Tried to hard wire and kept failing lighting circuits due to overload of the can communication. network.Wired this kit and lights worked perfectly. Assume it will work excellently for trailer lighting as well. Great part Thanks

Trailer Wiring
Have used two different harnesses on two different bikes. This was by far the easiest to install an was REALLY Plug-N-Play. Everything worked first time after installation. Would recommend highly!

Works perfect
Installed in 10 minutes and tested out perfectly, I am glad someone finally made a harness that is just for the 4 wire set up instead of having to buy an extra harness to go from 5 to 4 wire.

2015 Ultra FLHTK trailer wiring harness
This plug and play trailer wiring harness is absolutely spot on. Fit and ease of installation was refreshing. Operational in under ten minutes not counting tidying up.
