Wiring help!
Have someone step on the clutch and hold the key in the crank position. Check for 12V using a volt meter at the dark green wire at the starter relay.
If 12 V is not present at dark green under the hood at the starter relay then pull down the clutch safety switch under the dash. Disconnect the electrical connector hold the key in the crank check for 12V positive at the purple with white tracer. If 12V is present then use a jumper and jump purple to dark green. With the yellow with black at the starter relay grounded once you do the above the starter should crank.

If all of the bcm functions are not damaged it should then crank and fire with the starter relay installed under the hood.
If it does fire me personally I would unground the yellow with a black for the starter relay from the chassis and resplice it together solder and heat shrink and then verify everything still starts and runs normally.
All of the above wires you are working with are in the vicinity of the clutch pedal. Not the harness you cut out.

Repinning the harness for the 411 pcm pertains to and is related to the underhood engine harness only nothing else is touched. 98's have a bad rap for pcm programmability and it's limited because it is a one year pcm only. The newer pcms have more parameters to tinker and fine tune with. Just typical evolution of the species as the years went by. It wasn't due to any reliability issues.

However, that should not be a big deal to test to determine if it is the problem. That wire is simply a power feed that goes through the clutch switch and the starter relay coil to ground in the BCM (or in your case to a separate ground). You should be able to rig a jumper wire at the starter relay to provide that power directly, bypassing the clutch switch for testing purposes. For that matter, you could bypass the relay altogether - just pull the relay from its socket and use a heavy gauge jumper wire to connect the red wire at pin C4 with the dark green wire at pin B4 and see if the starter cranks. That eliminates the relay and all switches to simply test if passing power directly to the starter solenoid will get it to turn over. If that works then you can work back through to determine if the relay, the wiring or one of the switches is the problem.
