Before you removed the ignition switch, you could have done this :
1. Start the car with the key.
2. With the engine running normally, cut the Yellow Passlock2 wire near the ignition switch.
3. At this point you can stop and start the car with the key with no issues other than the Security Light on the
instrument panel will always be lit while the engine is running.
If you removed the ignition switch assy by cutting the wires, there should have been a group of three small gauge wires
in there. They are probably Yellow, Black ( or ORANGE / Black ) and White ( or RED / White ). You could try the permanent
bypass using any available value resistor ( a 1k ohm will work ). Make sure you have a fully charged battery.
1. Solder in the resistor between the cut Yellow and cut Black leads in the car. Insulate, heat shrink tube works well.
2. Power up the ignition leads and attempt to start the engine. It will fail but leave the ignition circuits ON for 10 minutes.
3. Un-power the ignition circuits for a few seconds and then do Step 2 again. 2nd try
4. Un-power the ignition circuits for a few seconds and then do Step 2 again. 3rd try
5. Un-power the ignition circuits for a few seconds and then start the engine. The new Passlock2 resistor value should
now be learned / accepted by the BCM and the engine should stay running.
I have never tried this on a vehicle where the whole ignition switch has been removed ( Black reference wire cut ).

Soldering is fun!
