Sorry, I forgot about that. Basically they are uploading the software to your existing computer.
Some one with tuning software will have to do it for you. They can either flash it on the bench with a bench harness or they can flash it through the OBD2 port on the truck. The newer operating system has more tables similar to the 03-07 PCM. They give you more options in to fine tune and control things.
Hope that helps.

Ive noticed the efans actually help keep the engine temp a little cooler than my old fan clutch!! I have them in my 99 hooked up exactly as they would have been in the 04-07vlassic trucks/suvs the only thing i lost was the auto recirculation when my a/c is off.... So i don't have fresh air coming into the cab when my ac/heat are off(which isn't often), which drove me absolutely ape!!!!!

I was about to say "how in the hell did you get those out, without braking the NSS and at least one of the connectors??"

Thanks! Good to know I'm going to stop by the wrecking yard where I bought to engine at he told me he will sell them to me for $100. I'll ask for the fuse box as well. Thanks for all the help

The pins are easy enough to pull out of the pcm harness, just take your time and be careful, bring a really small screwdriver or pick with you for removing the pins!!! I know its pin 42 on one connector and like 33 on the other and they go back inti the same holes on yours but as previously stated, you need to remove the pin goin to your ecm.... You may need to break the harness down and pull the wires for the fans out, not sure the headlight harnesses are interchangable though they may be,thought they used different headlamp bulbs or is it fog lamps??!!!
