Went to install my Prodigy brake controller this evening on my 2012 SM with 1550 miles. Plugged wiring harness into connector under dash and tried to mount the ground wire where it says to in the video on Tekonsha website. Couldn't even scratch the surface of the metal no matter what type of screw I tried. Was going to take truck down to neighbors (three houses down) as he's a mechanic. Started truck, and no matter what I do I can not get the truck out of park!!! During this time my 21 month old was sitting in driver's seat, but didn't really see him mess with anything. Why am I stuck in park? Help!!!
