Hey all. I have a 2003 F-250 7.3 that needs to go through inspection. My question is I know that they only check for emissions and the last time I went there with my dads Explorer, I saw them plug some wire underneath the dash near the foot pedals. I have a Bully Dog programmer where it looks like they would need to plug into to find out my emissions. Would I have to unplug this? And if I did, when I plug it back in should things go back to normal?
