The Corbeau is a generic belt, but should work out. On my XJ, I unplugged the sensor at one point (forget why, probably when pulling the soaked carpet) and never plugged it back in. If it's unplugged, it doesn't activate the light or annoying chime. Guys that run both 3-pt and harness belts will usually unplug the 3-pt so it doesn't complain when they're using the harness offroad.
Thanks Jerry. That answers my question!
