mechman777 Posted July 10, 2021 Share Posted July 10, 2021 (edited) The cts broke off into the head and I replaced it with a new sensor and pigtail, but cannot remember which color wires went to which pin. Does this even matter? 03 Sierra 4.3L Edited July 10, 2021 by mechman777 Quote Link to comment Share on other sites More sharing options...
