Backup lights not working

[PJ]

I have an 84 ford ranger 2wd I'm trying to get ready for inspection. The problem I am having is time and the backup lights aren't working. I've replaced bulbs. Also I have checked the Trans for the switch which had a broken wire. Fixed the wire and now the truck won't start? I'm sure it isn't the original trans, so any,help and advice is appreciated! Please move posts if needed. Sorry pressed for time. Thanks in advance!

After some research I have discovered the Trans is a m5odr1. I'm also pretty sure there is a couple of parts missing causing my backup light issue. After some Internet surfing I have found some part numbers but no name etc... the switch is 15520. The parts I am missing are 7392, 7c316, and maybe others. Looks like pins that would push the switch to close the connection, but where can I find more info or parts. Anyone?
