Harley trailer Light wiring 1997-2013

Carl Raymond on Apr 19th 2021

I received the kit and was able to install easily because of the detailed instructions! Lights on trailer work the way they supposed to. Will be taking a long trip with trailer and let you know how it goes Thanks for the product

Better than expected - Happy Customer!

The wiring harness showed up 2 days earlier than expected, well packaged and protected. Installation was a breeze because the instructions are well written. As the instructions explain, don't depend on wire color. Confirm function of the trailer's tail/running, brake, and turn signals wiring first before completing any connections. Go slow and everything will be ok. Even the length of the harness was perfect requiring no trimming to get the length right. Well done Dale! PS - I'm glad he kept the price lower by not including "standard" connectors because my old trailer is a 5 wire but with a rare square 6 connector.

Harley Wiring Harness + 4 flat converter

Sam Piper on Mar 25th 2019

I received the wiring harness and converter very promptly.. There are instructions with each component. The most important instruction is to "read the instructions." Following the instructions resulted in a 100% successful install on the first try. The only surprise is that a 4-flat (vehicle side) connector is not included in the converter. The connector is easily available at most auto parts stores. I've used the trailer a few times now and everything is perfect. Thanks Dale for all you support as I got through my trailer purchase and wiring processes.
