If you're diving into a classic truck restoration, you know how crucial it is to get the right parts. At BROTHERS Trucks, we've got your back with a massive selection of top-notch classic truck parts. Whether you're in the middle of restoring a cherished original or looking to add some personal flair with custom pieces, we’re the go-to place for all things classic and custom.

Take our Classic Update Wiring System for example. This isn’t just any wiring kit; it’s specifically designed for 1967-1968 Chevrolet and GMC C/K trucks. It’s packed with features that make your restoration project smoother and more enjoyable. Let’s break it down:

• The replacement headlight switch comes with an internal circuit breaker, so you won’t have to worry about any surprises. Plus, it includes a retention collar nut, an adjustable length shaft, and a custom knob for that perfect fit. We even throw in extra connectors and installation instructions to help you swap out your original headlight switches without a hitch.
• You’ll find standard turn signal and hazard flashers, along with a horn relay, all neatly mounted on the fuse panel. Everything is designed to fit in the original location, making it easy to access without getting tangled up in under-dash accessories.
• Speaking of accessibility, the fuse box is strategically placed to keep things clear of your gauge packages, wiper systems, and even heating and air conditioning setups. It’s all about making your life easier while you’re working on your ride.
• One of the standout features? Original switch connector bodies, exclusive to American Autowire. This means you can plug directly into most aftermarket steering columns and the classic GM columns from '69 and later. If you’re sticking with the original column, we’ve got you covered with the necessary connectors and terminals.
• We didn’t forget about your interior lighting either. The kit includes wiring for your dome lights, plus separate under-dash light sockets to brighten things up.
• For the instrument cluster, we’ve designed a "cluster harness disconnect" system. This makes it super easy to service and assemble. You get all the original terminals and connectors, but the best part is that you can wire in any gauge cluster package you want—be it AUTOMETER, CLASSIC INSTRUMENTS, or even DAKOTA DIGITAL. Flexibility is the name of the game.
• The rear body harness assembly plugs right into the main harness in the original spot, using existing retainers. We’ve designed it to allow for both original and custom routing, accommodating both pickup and suburban models. It includes backup light wires, connectors, and terminals for everything you need.
• Oh, and there’s a new floor dimmer switch included too! It’s all about keeping that original feel while ensuring everything works flawlessly.
• We’ve also included exclusive GM bulkhead connectors for your engine and front light wiring, making installation a breeze. Whether you’re going for original or custom routing, this harness has your back.
• And don’t worry about engine wiring—we’ve got connectors for both points type and H.E.I. distributors, along with power and tach connectors for GM H.E.I. distributors. Plus, we provide alternator connectors for GM "SI" series and "one wire" alternators, with the "CS" series connector available separately.
• Front lighting leads are extra long, giving you the flexibility to route them however you like, especially if you’re aiming for a clean under-hood look. All the necessary connectors and terminals are included, along with a switched trigger wire for an electric fan relay, which is pretty handy if you’re running AC.
• To top it all off, we include color schematics and straightforward installation instructions. No headaches here!

Check out the fitment details: this wiring system is perfect for the Chevrolet C/K 10, C/K 20, C/K 30 from 1967-1968, as well as the GMC C/K 15 and C/K 25 from the same years. It’s a solid investment for anyone serious about restoring their classic truck.
