I have a buddy with an 05 rcsb with 4.6. He has some cobra fans and i was wondering if anybody knows of any premade harnesses that would wire this up. Im hoppin its there is something already made for it because it would be nice to not have to manually turn it on every time he gets in his truck.

 

hayden makes a fan controller that will handle that job well. it is sold in most autoparts stores

 

Muchos gracias. Im gonna look that one up!!!!

 

i am going to go with a dc controller. i like the fasct that it doesnt spike the electrical system.
