neutral saftey switch wiring/ van tilt

[lt1CJ]

Hey I'm new here and I must say this is a great site! Quick question, I picked up a 72 shortbox 4x4, it was originally a 4 speed standard. Previous owner installed a th350/ np205, auto pedals and an auto van tilt coluum.The truck is not complete and not running at this time. I can see the neutral saftey switch which I know needs to be relocated, but there are no wires for the switch coming from the fuse block because this truck was a standard originally. Any idea how i can wire the switch and back up lights? Is there some sort of wiring for a clutch saftey switch on the standard tranny trucks I could use? Ive got the the factory assembly manual but cant find anything. You think after all these years someone would have numbered, put the pages in order and added an index in the manual. Thanks for the help guys!
