Yes, there are 2 outputs from the steering lock with opposite signal voltages feeding the BCM on pins 97 & 98, so it would actually be A & (!B). I think you could just hardwire to the unlock status and it should work, pin 97 12V, pin 98 GND - you would still get the key signal though but at least it would work and you don't risk burning out the expensive BCM (unless you screw up the wiring).

I tackle electronics from the "end user of the circuit(s)". Maybe you find my new thread "Steering Lock: cut a wire..etc" of interest...learned from all the circuit board connections within the lock itself. Hope it helps.
