If not, do you have four or six wire brake switch? You definitely need the six wire switch. I've installed cruise twice on P-body Shadows that didn't originally have cruise. Had to graft in wiring, add six wire brake switch, correct turn signal stalk, and have enabled SMEC in addition to obviously installing the cruise control servo. The first one no workie until I installed a SMEC that was cruise enabled.
