Proudly Designed, Engineered & Manufactured in the USA
All of our restoration wiring harnesses are manufactured in the USA. We’ve been doing it this way since our start in 1991.
We strongly believe in the value of maintaining American jobs and understand the quality of American made products can’t be matched anywhere else.
Adaptive Fit For Virtually Any Make & Model
Our kits are engineered to be compatible with virtually every make & model vehicle manufactured before 1979.
Almost all electrical components work the same across all makes & models which allows a Kwik Wire kit to adapt to your project. The electrical core of components like headlights, tail lights, gauges, starters, alternators, etc, work the same regardless if you’re building a GM or a Ford. They all need power and grounding. We engineer our kits to be adaptive to the vehicle it’s being installed which makes installation easy.

High Quality Wire
We only use the highest quality GXL coated stranded wire in all of our restoration wire harnesses. GXL wire is resistant to moisture, grease, oil, gasoline, most acids and solvents. It has a temperature rating of -59°F (-51°C) to 257°F (125°C). Stranded wire enables more flexibility in routing of the wire and offers more durability for applications where vibration and occasional movement of the wire could cause breakage of a stiffer solid wire or rigid stranded conductors.
To assist with the install, we also print the number and destination of every wire included in the kit every 4 inches the entire length of the wire. The number assigned to the circuit as well as the label are indicated in the instruction book as well, so you'll never lose track of what wire goes where!
The Best of the Best
The Best of the Best All of our kits were designed from the ground up with the goal of providing a quality American Made product that was affordable to our customers. Our kits are engineered and built as a universal cut-to-fit harness that will fit in virtually every make and model restoration while ensuring a perfect fit for your vehicle every time.
All of our harnesses come with a variety of features that all help make it the best kit on the market for automotive restoration. Below is a list of some of the unique features built into the design of our harnesses.
Engineered & Manufactured in the USA
Our kits were designed from the ground up and each kit includes 25+ years of exprience in the industry of engineering enhancements. Our wiring kits have also been proudly manufactured in the USA since our beginning in 1991.
Machine Crimped / Hand-soldered
We take the time to machine crimp & hand-solder every single terminal in our wire harness. You won’t find another kit on the market that gives this much attention to detail & quality to every single wire harness produced.
Coil Kill Switch
A coil kill switch is included with all of our standard wiring kits. When turned off, this switch keeps power from flowing to the coil of your car to keep it from starting. It’s a great theft resistance feature you can use during storage or at a car show.
Our kits are designed to be a universal fit. The truth is that almost all components hook-up the same regardless of make. Headlights work the same as they do in Ford vehicles as the do in GM builds. Our kits have been put in just about every make and model you can think of!
Instruction Book Included
An instruction book is included with every wire harness that walks through every single wire of the install. It’s easy to use and designed for even first-timers to use!
Toll-free Tech Support
We understand that not everybody has a degree in automotive wiring, so we’re here to help you out if you run into any snags. Give us a call to talk to one of our expert tech’s. You’ll be talking right to the guys who actually make the kits in Wisconsin!
Thicker Gauge Wire
We pride ourselves by producing a quality product, and that starts with using quality materials. We use more copper in our kits than many of our competitors. This helps ensure the safety of our product and longevity for years to come.
Plenty of Wire Included
Our wiring harnesses come with plenty of wiring for your build. The kits are designed as a cut-to-fit harness to ensure a perfect fit every time. Each kit comes with 25 ft of wire to the tail group so you’ll most likely have plenty of left-overs when you’re done.
Pre-wired Horn Relay
Beep Beep! All of our kits come with a horn relay pre-wired into the kit so you don’t have to figure out how to wire it up later. The kit also comes with instructions on how to hook it up. You’ll be honking away in no time!
Pre-wired Fan Relay
Standard wire harnesses come with a pre-wired electric fan relay in the kit so you don’t have to figure out how to wire it up later. The kit also comes with instructions on how to hook it up. It's simple to keep that engine cool!
Speaker Wire Included
We include speaker wire with all of our standard wire harnesses. The plastic jacket around the speaker wire helps to deliver high-quality undistorted signals to and from all of your audio equipment.
Stainless Steel Fuse Cover
All of our standard wiring harnesses come with a brushed stainless steel cover to protect the fuses. Labels indicating what each fuse is for are also located on the underside of the cover. Oh yeah...and it looks great too!
Aluminum Mounting Plate
Our standard kits come with an aluminum mounting plate installed to the underside of the the fuse block. This plate helps protect the wires where they go into the block as well as allow you to mount the fuse panel securely in your vehicle.
Full-size ATO Fuses
Some kits on the market cut corners by offering a fuse block that uses mini fuses. Mini fuses can be hard to come by when you need to replace a fuse the most. Our kits use full-size ATO fuses that you’ll be able to find at just about any gas station or hardware store.
