Pretty much what Batman said, you need to tap into the circuit that turns the starter relay on at some point, either between the ignition and the relay or between the relay and ground, and cut it, run each wire to the clutch start switch on your clutch pedal. If you don't have the plug for the clutch start switch, you'll need to get one.

I have a spare switch if you need it. It's the black w/yellow stripe and the black wire from the shifter harness. You need to cut them and connect one (black) from the ECU side and the other (black w/yellow stripe) from the harness side, and have them go to the switch. It might be reversed, I just can't remember which way it goes.
