LawyerRon,
Never replaced it on a Tundra. Don't think it's that difficult though. I'm inclined to buy the part, look at it, figure out basically how it works, and install it. If it doesn't work or you can't get it on....... take it back........ no harm done(usually).
Frequently, AutoZone has directions for R/R of alot of the stuff they sell. Don't know if the TPS from AutoZone is of high quality or not.
If Mustang67408 is around, maybe he'll chime in here with some step-by-step.
I've PM him, so hopefully he'll pop in.
good luck,
