Bruce, My mechanic has one sitting on his desk, I saw it this morning. Mine went bad and I drove around for a year without cruise after swapping out two throttle cable units, only to find out it was the brain. It is nice to have cruise back. You should be able to swap one out of John Stein's car to test or maybe my car down there in Marietta, Call Scott and see if the car has cruise, he'll let you use the unit for diagnostics. They fill with water and corrode. steve
