Hardest part was trying to find room to mount the remote controller and relay! You can see I ended up installing the remote controller beside the battery, perfect fit and already a hole there. The relay was a little harder. It's down behind the battery tray on the passenger side fender area. Tapped into the fog lights. Work great!

 

I'm working the same setup today. What did you do with the parts that were sitting where your wireless box is?
