21 Circuit Classic Customizable Bulkhead Harness
This 21 circuit universal kit is great for hot rod or street rod builds, but you'll find that it's easily adaptable to almost any vehicle and has enough length to handle full size and muscle cars. To pass through the firewall, a bulkhead connector is utilized, giving you the ability to disconnect the engine/headlight section wiring at the firewall. The provided to-scale peel and stick template makes firewall trimming easy. This harness comes with open ended ignition switch wires that can easily be adapted to any ignition switch out there. Included with this harness are the following parts; a GM engineered fuse block and bulkhead connector; GM turn signal connectors; pre wired plugs for the headlights and dimmer switch; and each wire is printed with the circuit identification as well as using GM color codes for easy installation.
