there is a Fan1 and Fan2, he shouldn't have an problem locating them. I will say tho, I would be very cautious about having someone tune your car who hasn't dealt with the way GM handles tq management and similar. I had a very good local tuner do mine, and after sitting down with a an o.e.m tuning engineer, we found issues all over. You can make a car run decent on a crap tune and never be the wiser until it blows up.
3) on lt1swap.com it says we can use a pin for a tow haul mode
Hart Rod and some others had a thread on this a little while back. If you dig back through the Lsx section they have a few pages on setting it up. The GenIII and GenIV handle it a little differently.
5) the tach output pin, I have an older sun 8k tach, what do i need to do with the one pin that i have on the ecm?
I may have more questions... but im not by the truck so i dont remember anything else atm. thanks for any input

There is a thread called Conventional Tach on LS2 that gives the part # for a pullup resistor allowing the use of regular tach's
