Any one install one in a 96 model . The instructions start out with the 97 model . I had to bend the brake line from the master cyl. to the combination valve ,those lines do not bend easy . Every thing was fine during test run around block with out trailer . I then took a 15 mile trip and now the units is reading 68 lbs. of line presure with out any pedal pressure ,and wont go off . This causes the brake lights to stay on all the time so right now i have it disconected . Any one have an idea what happened . I sure hope i didnt mess up the ABS system . Arnie
