Firstgear Battery Harness 4.8 5 5 5
Simple Part I don't believe this is on the website, I just asked my customer service professional about a First Gear harness while I was ordering something else. Typical Revzilla, they had the part and even suggested the shorter harness length since I was using it for the rider instead of the passenger. August 10, 2015
Just what I needed As ordered, easy to install, quality part. Looked around but only found it on your site. December 8, 2014
Works perfectly, easy to install. I have a First Gear heater set up on my Harley Davidson. This simple device now allows me to also use it on my Kawasaki 900 LT with out having to move the set up from one bike to the other. This is allowing me to put less miles on my more expensive Softail during the harsh winter months but still allows me to get my knees in the breeze. Perfect addition to anyone with more then one bike and who won't let the weather conditions slow down their passion for riding. Installation only took about 10 minutes. November 24, 2014
is good for other things to plug in this was a good product and i would get another for my other bike October 28, 2013
Worked well with minor modification. The cord is very well made, durable and functional. However it was too short to reach an accessable area from the battery to plug in to until I added 12 inches of additonal wire. May 31, 2012
