No problem.
Corvette C5 97-04 Column Lock Bypass Kit
Applying +12VDC is all the single pin inside adapter on the left at the link does; the ground is the vehicle.

I know someone who bought one that is what a continuity check showed.
Mine locked because I let the battery voltage drop. After it happened it was a real wake up call so I ordered a kit. Installing one when there isn't a problem is easy. My recommendation would be buy one and install it before the educational experience.
I bought the Compliance Parts unit as it has the most professional made look to it.
All they are is depending on your source $12 to $20 in parts:

I found this but by the time I would have bought all the parts and paid S&H from multiple sources, it was a lot quicker and less expensive to buy one already made.

Q. Is there a way to unlock the steering column in an emergency, or if I didn't get an Unlocker?
A Yes. There are a few ways. But, due to legal and safety concerns, we do not provide complete information on a procedure that may damage very expensive parts of your Corvette's electrical system. If you have an emergency, i.e., your Vette is stuck somewhere and the risk to life or property outweighs the relatively small risk of damage to the electrical components, please contact us and we'll try to help.
Basically, the steering column lock motor wires are briefly connected to 12 volts and ground. The LMC5 Unlocker contains a fuse that protects you and your car in the event that you accidentally touch the wires together, to ground, etc. Also, by performing the unlock procedure as recommended during the LMC5 installation, the risk of incorrectly connecting the Unlocker is virtually nil.

I hold an Extra Class Ham ticket; so I approached it with a lot of research and still called a bud for a continuity test as I know the internet.
I do not understand IF the device works and they do work why the GM fixes need to be uninstalled. However, that is what some of the advice is; to do a T or F test, I'd need to see schematics for the fixes.
However, I would be very interested to learn how these kits with the device furnished on the left at the first link and others "
briefly connect the lock motor wires."
Edit:
There are two harnesses, the original and the GM "Harness K" GM part no. 89023816 fix so there could be some truth in the uninstall the fix depending on what GM changed??
