2014+ YFZ450R manual fan switch install

How to install a manual fan switch on a 2014+ Yfz450R.
This project is pretty easy and covers any model Yfz450R as long as it’s a 2014 or newer.
This set up works with the key on or off. But doesn’t cut into the wiring harness at all, so the fan will still automatically turn on of quad reaches its temp level on its own.
I would rate this project
At a 2 out of 5 stars on difficultly
