If you don't have a chip/stutterbox, just unplug it, and you can start the car without pushing in the clutch. If you DO have a chip with a 2-step, you just need to do the clutchwire/diode installation like normal, but leave the end of the wire disconnected that runs off into the harness. You actually don't even need the diode in that case, since you no longer need to isolate the starter relay from the ECU. So, you can just:
1) cut the black/red striped wire coming off the lower clutchswitch connector
2) connect a straight piece of wire to the end of the black/red striped wire that is still connected to the switch/connector
3) tape off the other loose end of the black/red wire that goes off into the harness to the relay
4) cut the black ground wire loose from pin #104 of the ECU
5) connect the other end of the straight piece of wire to pin #104 of the ECU.
