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.

This wire harness is specific to the following vehicles: FITS 1969-74 NOVA, EL CAMINO, MONTE CARLO, CHEVELLE, CUTLASS, SKYLARK, TEMPEST AND GTO. INCLUDES PRE-TERMINATED PLUGS FOR IGNITION, TURN SIGNAL AND DASH. If looking for an exact replacement harness for your car you many want to contact Painless Wiring direct. We also offer a universal harness and fuse block at an economical price of $149.99 under part number 91064027 that would require cutting to the appropriate length and installing the proper ends or splicing into the existing wiring. It will NOT be a direct fit for the firewall mount fuse block and junction block.
