Speedway part number 91020102. This universal GM type wiring harness has provisions for right and left high and low beam headlights, turn signals and park lights. The tail section wires including tail lights, brake lights, turn signal lights, fuel gauge sender, third brake light, and reverse lights. The wiring that comes in the harness, does not have all of the factory style connectors installed, so you can wire the marker lights to the park/running lights and have them on anytime the park lights are on.
