The smaller connector on the park switch has 6 wires I think. Most vehicles have one type of connector for the front and the other for the rear to keep them from getting mixed up. It's tough to say for sure if they're all the same but I'm gonna say yes as well. The harness length and connector type is the greatest difference (although later systems have different vendors and some have a different type of ground). The ones that physically look different, probably are.
