Wiring up a "tow haul" switch and using it as a drop gear button..
The truck scene does this a lot by making their tow haul switches a drop gear button for rolls...
on LS swaps i've used a momentary switch grounded to pin 71 on the blue connector...
any of you guys run a setup like this?

the way we always did it was setup erase the Tow haul transmission table and start with a Drop Gear one from scratch... doing it this way avoided having to manually drop a gear by the shifter.. The way the tables are setup are so that the PCM knows what gear to drop down to depending on what speed you're going.. 30 roll drops you down to first and so on..
it's pin 71 on the blue connector for the PCM. you wire up a momentary switch and have your tuner adjust the "performance" table for a drop gear table
i have a write up on it on a few sites.. here is the more detailed one.

Would this work on my LSx swapped mustang? Because this would be fantastic!
What I would like is running 55 mph, hit the button, and bang, 2nd gear WOT powah to the ground. Or am I missing something?

finally got around to doing this, it works and it helps alot with racing against m6 guys or any other manual transmission car. all you do is hit the button, give it a little bit more pedal, and the trans will downshift and hold the rpm until the pcm sees a 100% tps reading
