I was afraid you would ask that! I mounted the alternator myself, it took some calling around because some shops around here (palmdale CA) had no idea how to go about it, which is sad considering its not that difficult in hind sight. I paid $180 bucks to have ot all wired up, but the guy did a great job, I told him what I do with the truck and I need it to be reliable etc... so he ran a lincloln town car harness to handle the extra output. This does sound rather high but I didnt mind since i knew it was done right. But that cost is only wiring it up, not installing a different alternator. Man im long winded tonight sorry
