I'm assuming that there would be no issues with tieing the output from the lock controller into the wire from the light switch that powers the tail lights.
Does anyone know which wire in the wiring harness below the steering wheel is the park lights?
That would be easy to figure out if you have a multimeter.
Or do a back trace from the tail light.
