The directions are confusing and wires it say are on left side is incorrect.trying to make it work.the wires connections are not sealed to keep out moisture.

Delivery was much quicker then I thought it would be.

The only thing I was Not happy with was the covering on the wires was a basic black plastic not the nice fancy webbed covering like in the picture that is shown on the website. I was also surprised when I found the same exact one and part number on another site for way less money but I'm loyal to J and P because of customer service.

Great filter. The bolt head / ability to use a boxed end wrench on it helps with the tight fit on my motorcycle.

Great to do business with will always order my parts from here I have a 1994 Harley and it’s hard to find parts for but J&P cycles make it easy just give them a call

This harness made my life easy on my 73 shovel, all wires matched great, there was minimal fab work to mount it to my frame.

Quality product with detailed installation instructions. Just took a bit longer to arrive than anticipated.
June 16, 2020
Wiring harness was perfect but the wiring diagram not that good, it only helps for direct Harley replacement but I was able to make it work with a simple diagram and understanding what the wires were for. Got it hooked up and the first test fired the bike right up. Thanks!
