PCM Output for TH400 Kickdown? I'm th400 swapping a 1994 Trans Am. I'm completely new to the efi tuning and ecm hacking game, everything I grew up with had a 4bbl...
I was trying to plan where to put a WOT switch for the electric kickdown on the th400 when it dawned on me that there's already a TPS. Is it possible to to set up the pcm to give a 12v output when the TPS is 90% or higher? For instance could I use the EGR or AIR outputs that I might no longer need and have one of them energize at WOT only?

Unfortunately no. pull shifter down one click haul *** mode engaged.
But B&M makes a switch that mounts to the throttle cable bracket and connects to linkage that will do what you need too. Just gotta hunt kegs and summit.
