where is neutral safety switch

The harness for the NSS will have a 3 pin round plug on the trans end and it will come up into the engine bay and connect to the starter relay. The middle pin is grounded @ the trans when it's in park or neutral(brown w/yellow). the outer two wires are for the reverse lights This Bn/Y wire grounds the relay and closes the contacts in the relay only when cranking (Yellow wire from firewall bulkhead/ignition switch only hot when cranking). Do you have any photos of this middle plug or the connection your unsure of? I may be missing your ? altogether.
