2003 GMC tow/haul switch input signal to the body control module location

I seem to have lost the ground to my Tow/Haul button and the wiring is okay in shifter just has no ground so I need to know where to look for the grounding post or nut where ever it is. I have the wiring schematics so I just need the location(s) so I can find it on a 2003 GMC 3500 4x4, 6.0 engine, auto trans
thanks
