If you suspect that G402 is not connected to ground, you can install a new ground connection. Splice into the black wire, crimp on a ring terminal and put it under a metal screw into the metal body or frame. Extra points for sanding the paint off the area and coating with dielectric grease to keep the water out.
I am looking for the location of a G402 Ground for a 1999 gmc Sierra 1500 4.8L
