oh damn, I've been wanting to do a conversion for ages. What all does the install entail? Where did you get all the parts, fans, harness, etc? Does it have a temperature unit to turn on/off the fans and do they turn on when the AC is turned on?

There was a post on one of the hummer forums. I bought the 2007 truck shroud and fans. I modified the shroud to drop on but never went all the way. It also includes the wiring harness and relays that run of the factory computer. You have to have get your ECU updated to let it know you have fans and it will turn them on and off. Everything you need butt he ECU modification is included. I think I have about $600 in it so far. I am selling my H2 so I don't need it.
