Need help with back -up lights

I've been working on getting all the lights on my 78 F-150 Lariat to work. All the interior ones work and even installed a factory AM/FM after getting all the pieces. Only lights not working are the back ups. I replaced the bulbs,check for power at the fuse box. They still don't work. The trans was rebuilt six months ago .Is there a connection they could have missed ? Is there a backup switch that could have gone bad ? It's a C-6. Neutral switch ? Any ideas ? Thanks for your help.

Mine went out like that on my C4. NS switch was on tranny. NS worked, but reverse contacts were shot. New switch isn't cheap...the ones that mount on the tranny.

Tetraruby, Thanks for your last post in this thread. That answered my question. Is there a way to test if the back up light switch is bad....or is it just a replace and see?
I have a c6 with the transmision mounted NSS/reverse lamps both on the same switch.
Mike

You can try probing the plug that should be near the firewall. Be carefull though, the wrong short can cause the starter to turn over.
