i replaced the fuse, the headlight switch as well, and checked for corrosion the bulbs, replacing them with new ones and add another ground from the instrument cluster. and still can't get the gauge lights to light up. i do have the turn signals and high beam indicator as well as the seatbelt notification. I believe the grey wire from the cluster is lights? should I trace the wire and look for any kinks I'm lost right now, any advice would be appreciated.
