19Cutlass94 Posted July 29, 2013 Report Posted July 29, 2013 Does anyone happen to know what color wiring going into the pigtail is for the tach? Looking to tap into that wire. I dont have a wiring diagram handy. Thanks Quote

94 olds vert Posted August 7, 2013 Report Posted August 7, 2013 Is the 89 setup the same? I'm not quite sure what you are asking. 88-91 Cars have the same wiring. In 1992 the wiring changed. Quote
