I had pulled the bolt out to add a ground and heard something fall when I pulled it, not that something broke. I looked everywhere for a diagram like that and appreciate you sharing that! Is there a way to run the bolt back into the HVAC box without pulling the dash out?

Nobody?

Long story short I had a lifter go out so I built a heads/cam motor. I was wanting to add another ground and pulled this bolt. When I did I heard something "fall" sounding like it was in the dash in the cab. Does anyone know what this goes to and if so how I can get to it? Now I have a thud noise after I hit bumps and its very annoying.
