Is there a pre-heater hose that connects to the air box? What is the small retangular opening in the inside front of the air box? What is the retangular box connected to the outside if the air box, next to the battery? Thanks, Bill *** For what its worth I contacted the US border folks and told them about my clock and odometer getting zapped and they not only could not give an explanation but did not even want to discuss it, however I was able to talk to a Canadian official who said that there is a substantial amount of Microwave and "other" technologies used on both sides of the border. She had never heard of a car clocks time beong changed or the trip odometer being reset....but they have had cars electronic ignition malfunction to the point where the car would not start! Interesting.....Bill
