transamcreations.com is where i got mine becasue they only sell fans that def work but u can get em anywhere and as far as the nelson harness u can get at Nelsonperformance.com and comes with everything you need and as far as installing it goes it couldnt be any easier just look at the pics in my cardomain thats basicallt it exept u hafto plug a pin into the pcm which is also real easy it comes with detailed directions with pictures too the hardest part about the install is getting the mechanical fan off... get a strap wrench trust me it makes it sooo easy .. i didnt have one at first and i ended up haveing to go get one the next day.. it sucks getting half way through the project then havein to wait till the next day to finish
