Neutral Safety Switch Problems

Alright, i've been working on my 1974 mustang ii for a while now. I recently put the 302 back in and began getting everything put back in. I bought a B&M shifter for it and forgot where the neutral safety switch hookup is in the engine compartment. i think it is a four prong connector that is on the firewall. Any advise?
 
The wires for this connector go though the tunnel right about where the gas pedal is on the inside. if you removed the entire piece the connector I believe is on the inside on some of the year (someone correct me if I am wrong).

Good luck,

Tim
