neutral safety switch

Bad news, before I put 50 miles on the new transmission it started slipping out of gear and not shifting properly. It would get stuck in neutral and would occasionally shift into drive for a minute or two, the dash PRNDL lights are all hardly working. Obviously my first instinct was to replace...

I've watched a few of the vids on an '05 about changing the Neutral Safety Switch, but when I jacked up the truck and took off the wheel, it did not look the same. Can anyone tell me where the heck it is? My truck won't start, and I've got the part to try, just can't find the dang thing!
