Cuda,
LOADMASTER. 4-wheel disc brakes. Radial tires. Reverse lights on the Jeep actuate the electrically switched reverse lock-out on the actuator. No need to jump out and throw a switch. Just put the Jeep in reverse and back up lights circuit on the Jeep tells the actuator not to engage the brakes. Uses a 5-pin connector. Jeep already has a 7 pin outlet. Simple off-the shelf 7-to-5 adapter.
