I have multiple TCM files, the 2001/2002 OS will not activate the Factory OD/LO without the added momentary on switch as others have stated.
Also if you use a 2003-2005 OS in any 2001/2001 truck the "D" indicator will not light up but will still work.
If you need a copy of others just ask

By the way Tony's file worked flawless
Do you have to run a wire or would it work in my 05 by just pushing the odlo button?
Would any 01/02 tune work that way in my 05, or is running the wire the only way?
