      Surprisingly easy. Watch the video and step by step instructions it's no big deal. It took me a full day but I went super slow.

      Worked great!

      I’ve never done any sort of serious wiring on a bike before so I was a bit nervous about attempting this. It took me a full day to complete, I went incredibly slow so I could understand exactly what I was removing and what the new wires did. It comes with detailed instructions and I would suggest watching the installation videos available online as well. I’m super happy with the result, my bike started right up and now I’m more familiar with every wire on my bike. A great product and a great learning experience!

      Works

      Easy to do but if you’re using it with the gas box motor mount/coil/ignition relocator then you’ll need to connect another 2 feet of colored wires from near the primary back up the backbone to the ignition/coil mount. No biggie. Once you’re this far what’s another day? It’s MUCH cleaner than the stock harness

      Awesome! Very easy to install

      Let me say this. When deleting the nerd sh*t off your bike and you accidentally cut some sort of ground and your sitting there testing it for hours trying to figure out what went wrong, just save yourself the time and buy this awesome kit. It’s very easy to install, I am so happy with the product, it came with awesome packaging, instructions for everything ! Absolutely satisfied with this product . Would recommend 100 percent weather you just want to lose all the wiring junk or messed up something like I did, CLEAN!

      Bam!

      Incredible product and the harness itself is exceptionally made. The ignition switch itself is cheap and untrustworthy. I would've gladly paid more for a higher quality option. Other than that I don't regret this purchase a bit.

      Fantastic Harness and Looks So Much Better

      Cutting out my stock harness was so satisfying knowing that this slim new harness was going to replace it. Super easy tear out and install. The guide that's sent with it and the youtube video Lowbrow has made it even easier and helped me get it done in no time flat. The only part I don't like is the keys seem kinda flimsy and I'm not the biggest fan of where the ignition mounts otherwise I definitely recommend this harness for a simpler and less clustered looked.

      Wiring Harness

      This harness allowed me to delete a lot of the unnecessary stuff on my bike that I've been wanting gone and gave my bike a nice clean look. It was easy to put together too

      HQ wiring harness

      Video for install makes this a breeze - really cleaned up the bike instead of the stock wiring harness that’s more like a rats nest. Love the quality of the ignition and the loom.
