OK cool let us know how it goes once you're done. I didn't go the resistor route cause I didn't want to tear into the column. But cranking up fine and then shutting fuel off after 2 seconds is EXACTLY what Passlock does when it's working. Or more to the point, what it does gradually more often, and eventually all the time, when it's NOT working...... I have also read on here from longtime members who have done the resistor thing, that eventually the resistor has too much resistance to work properly. Seems to me that a lot of electrical stuff is made to work for X number of duty cycles and then it quits. Electronically deleting the Passlock function from the computer with a tune is like removing an app from your phone. Once it's gone, it's gone until it gets put back in the same way. Which I wouldn't do unless I had a new control box and a known good spare one..... Unfortunately not everything is easily obtainable for these trucks! I do understand the resistor is much cheaper than the tune though!
