Steering Lock: cut one wire. /switch optional

Dwight Frye

From my admittedly limited knowledge of the circuits involved with the lock, I think all of the other wires except the brown one have to still be connected to the lock mechanism as there is some kind of loop through or feedback from the lock module to the BCM. So you could probably completely remove the lock assembly but you would still have a bunch of wires that need to be connected.
I'll just leave the lock assembly in place and not worry about it if disabled.
