Hi everybody, just bought a 2003 AV and I am planning on doing the E fan conversion. I have a harness from an 05 Tahoe plus the fans, I also have the fans from an 08 Escalade. Now my question is which fan should I use? One has a 7 blade with a 5 blade and the other has dual 7 blade. One other thing I might add is none of the videos I watched showed anything about taking the fuse box cover along with it, it has the fuse access cover on it might as well take it to make things easily accessible. I know it'll take more power to run, but I already did an alternator upgrade to 145 amps. I know some of the responses of fuel economy and hp may arise, I'm looking for the quietness of the engine bay aspect also
