screamindriver, YOU'RE THE MAN! Thanks to 1 WILD RT's detailed troubleshooting instructions, I got the backup lights to work with the jumper on my neutral safety plug. I took the switch out and shaved a bit off the pin and now my backup lights work! I can't believe the pinheads who make this switch would make the pin too long. You have no idea how many hours I've spent trying to fix this problem. I just assumed the switch I bought was good, because it solved my neutral safety problem. Now maybe I can get my elusive inspection sticker so the cops will leave me alone. Thanks again to everyone who helped me with this incredibly annoying problem!
