Same as before "what?" It's really simple. The center terminal goes over the transmission up the firewall and hooks to the one spade / push on connector on the starter relay and grounds it. If that does not work, either the switch is bad, there is something wrong in the internal "rooster comb" (loose) or the shifter is out of adjustment.. Probably THE no1 troubleshooting aid is to wiggle the shifter when twisting the key. If it clicks/ cranks then the shifter / linkage is likely just out of adjustment.
