I ended up buying the $40 AC delco pigtail for the pedal, since my TAC module had a pigtail end in it.
I contacted several salvage yards, and most of them responded with " I won't hack up a wiring harness just for the one wire you need "
Or " I'll sell you the whole wiring harness, and you can cut out the wire you need "
Even though I would explain that this piece isn't even part of the main engine wiring harness.
Oh well, problem solved anyway
