I am new to the site and new to Cummins, doing lots of reading and research, I am considering replacing the TPS with a potentiometer. Has any one done this, does it work as it is billed on some of the other sites? Now for the really dumb question, yes I am fully prepared to ask DUMB QUESTIONS; where is the thing? Is there a pic out there, maybe?

I think theres a few auto guys around here that can help you. I have never seen an auto 12V personally. My book shows the TPS as being right on the side of the injection pump, the front portion of it. You will see a bunch of cables and springs.. Not sure on the potentiometer, sounds like it would work but know nothing about how it works on these trucks. Ask all the questions you want, we encourage it here. The dumb questions are the ones you already know the answers to, which neither of us did so they must not be dumb
