If you want to keep your race car streetable and want to use all of your factory switches instead of a switch panel, this 21 circuit harness is for you. As with all of our chassis harnesses this kit has all the wires labeled and is pre terminated at the fuse block for easy installation. This harness includes an optional connector if you want to use a GM column mounted ignition switch. Also Included is a terminal assortment kit, with the necessary connectors for your turn signal switch, headlights, and alternator. Each wire is custom printed with the circuit identification as well as using GM color codes for easy installation.
