Thanks for the feedback on your experience and these questions. I am considering doing what you did since this thread has not generated the ideas I thought might be out there.

May I ask roughly what was the cost? Did you do all 4 corners? Were you able to reset the flashing "SLS Inactive" message on the dash so you don't have to stare at it? What is the status of the lights on the rocker switch? Thanks again.
