THIS BUY IT NOW AUCTION IS FOR CADILLAC 1970 THROUGH 1977. IT IS A NON RESUME 3 TERMINAL TRANSDUCER THAT WAS DESIGNED FOR CADILLAC & BUICK. THOSE TWO MAKES OF GM OF CARS HAD A 3RD TERMINAL ADDED FOR A CRUISE LIGHT ON THE DASH OR SPEEDO CLUSTER THAT WOULD SAY CRUISE WHILE IN CRUISE MODE. IT IS ALSO DESIGNED FOR 1970 THROUGH 1980 BUICK VEHICLES. AS THEY OFFERED THE 3 TERMINAL ALSO. I HAVE RECONDITIONED IT THE BEST POSSIBLE AND WILL WORK A LONG TIME AS I TEAR THEM DOWNÂ THEN BUILD THEM BACK UP TO HAVE YOUR SPEEDOOMETER SMOOTH AND CRUISE CONTROL WORKING TO FACTORY SPEC'S. I HAVE BEEN DOING THESE TRANSDUCERS SINCE 1978 AT A COMPANY I WORKED FOR. THEN IN 1984 I STARTED MY OWN COMPANY CALLED CRUISEMASTERS AND HAVE BEEN OFFEFRING THESE PARTS SINCE. . WARRANTY IS 1 YEAR AS I KNOW SOMETIMES A CUSTOMER WOULD NOT BE ABLE TO SEE HOW IT OPERATES AS THE WINTER WEATHER APROACHES SO I LIKE TO HAVE THEM WARRANTEED THROUGH 1 YEAR TO BE ABLE TO USE IN THE SPRING SUMMER SO FOR CERTAIN THEY WILL KNOW AND BE HAPPY THAT IT WORKS ERFECT. I OFFER REPAIR AUCTIONS I OFFER ALL GM CARS & TRUCKS FOR ALL THE YEARS 1970-*1983. PLEASE SEE SELLERS OTHER ITEMS.
