You have a manual? If not the 72 is fairly close, here are the downloads:

Personally I see no real use for a clutch switch, but the replaced the neutral safety switch on the auto. The switch is grounded, the other wire comes out through the firewall in a separate grommet, and hooks to the remaining "push on" terminal on the starter relay.

I assume when you say three wires you are talking about the harness that goes down to the trans. Don't use the center wire, which was NSS. As I said, if you use the clutch switch, it comes out the firewall separately.

Replace the auto three term. connector with whatever fits the gearbox, and wire the OUTER two wires in that harness to the backup switch, should get you going.

OK, it's simple. If you only have a 3 terminal relay (only one push on connector) the relay is for a STICK car WITHOUT clutch safety. If you insist on using the clutch safety, you'll have to buy a 4 terminal relay, simplest way is ask for one with an auto
