You must drain and remove the radiator from the bike in order to install the fan. Picture is correct with only one rivet on the outside, 2 on the inside. I had to remove my tank to locate the connector but others have been able to find their connector without removing the tank. One connector goes to the bike harness and one goes to the fan (I think the directions state both connections go to the bike harness). When done, just fill the radiator, run the bike and check fluid level. Top off if needed. To check operation of the fan I let my bike idle for approximately 7 minutes. Fan should go off a couple of seconds after shutting the bike off. Locate your fuse for the fan where you can access it easily on the trail if need be. I have not had any boilovers since installing the fan.
