well to see if it is your switch put a metal paperclip between the outter 2 terminals of the boot on the Neutral safty switch, throw in R, and if the lights come on it's that, if not it's wiring. I got a new NSS from advanced auto for $12. Only problem is that the plunger isn't long enough for when I throw it in R to make the connection. I got one from Napa but the ends that go into the plug are too long and big. I suppose machining them will work
