well i ordered a tci they shipped it today. i read that gm map sensors will work with it. the one mentioned was 89.00 here. I found one for 39.99 fits buick and chevy its a master pro 2-ms21 from o-o you know the rest. had to put a adapter on hose to use the dorman47311
looks and sound like a straight forward conversion. hope the computer program is easy. the display on laptop looks like modern salt spreader programing {same format}. now the waiting game. ps. i asked for 3 terminals or part numbers to source locally.
