Recently purchased ultra cool auto cooling system for my 05 Harley Road King. Very easy installation just ran into a few snags. One being I had to reroute a rectifier wiring harness from underneath to over the top and behind rectifier in order for cooler to fit cooler bracket .Secondly, rectifier when I was finished was hitting oil filter housing . Had to remove rectifier and just bend rectifier bracket slightly to get clearance .Just road one day so far with a bunch of buddies and all were impressed with the cooler installation and how it looked. Thank you Ultra Cool
