Hi Sachem, thank you for the reply,

first of all i fell prey to the broken steering column shifter wiring so i had to test that first, and decided on a new button location.

once i relocated the momentary push button tow haul mode was activated and the truck shifted differently and the indicator lite was coming on and going off in the dash.

i do notice that the indicator light goes out after a few minutes and tow haul is shut off.

all of this is achieved without pin 71 being connected or being enabled for now. i will look at the transmission parameters and see what is set up.
