Cant get it to turn over

What happens if you jumper across the starter relay? This tells you that the big wire down to the solenoid is OK

If that operates the starter, then determine if it's

1...the relay

2...a wiring problem or the NSS

3...a wiring problem or the ignition switch.

To do that, identify the wire going FROM the relay (small push on terminal) down the firewall and to the transmission. Remove that wire from the relay. Take an alligator clip lead and jumper that relay terminal to ground

Try the key. It should crank.
