I'd need the Service Manual to have a fighting chance of knowing where it is and what it looks like. (I wouldn't recognize a Stryker if you parked it in front of me)

Following the ground wire from the coil would reveal it except that usually wires are wrapped into bundles and that obscures where they go. Maybe the wire is color coded (wire body color and stripe) such that you could recognize the other end?

Is there a way to bypass ignition module so you can see if its bad?

Maybe. Depends on whether the circuit includes resistance or not.
In the old day of cars with points & coil ignition systems you could apply 12V to one side and use a jumper wire to the other primary to ground the coil and test for spark. But that's because those coils could handle the current flow for a short intermittent grounding test to produce a spark.

This would be testing that the coil is good and the spark plug wire is good.

Ignition module - service manual might give some resistance readings for it. (you need a meter and not a test light)
It's possible that a service manual would give a test procedure.
The service manual would give resistance readings for the coil primary and secondary circuits and probably readings for the timing pickup.
Maybe for the module also.

Edit- no bypassing the ignition module. It's there for a reason and is very difficult to mimic with anything else.

Given that this all started because someone was screwing with the ignition switch and the bike was running beforehand (was it?) chances are real good that the ignition module is ok and the real problem is that it's not getting power or signals to it.

With the circuit diagram it would be good to find where to apply power to the ign module using a jumper or to just test for power at the terminals that should have it.

Oh and with the wiring diagram/service manual you could test for the kill switch functioning correctly too.

Without a service manual, a wiring diagram, and a volt-ohmmeter troubleshooting requires a lot more luck to be successful.
