Made in USA

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!

Labeled Every 4 Inches

14 circuit harness

Posted by Richard Anderson, Anderson Enterprises, Funk Nebraska on 23rd Aug 2018

Probably the 5th or 6th harness of yours I have used. Very nice product. LOVE the new instruction book as opposed to the small paper back one. It would be nice if all harnesses had the electric choke wire, as that is often needed even in a ride that would not require all the bells and whistles of the top 2 harnesses. Overall, I really like your product.

For what it is, I think its a fantastic deal. Everything is laid out perfectly......and labelled everywhere! Being an electrician by trade, it may be easier for me. I have not installed it yet, but I have looked at everything and I am impressed. You wont find a better harness for the money and with the good instructions too. Two thumbs up!

Very happy with my purchase.

I spent a few extra dollars over the competitors with this wire kit, and it was well worth it. My first complete wire job, end it was a breeze. And converting the 24 V system to 12 V was a snap! From the labeling, heavy gauge wire, and directions, I couldn’t ask for anything more. This vehicle I had a aftermarket wiring harness was a complete rats nest. Thank you !!!

Great kit for many different projects

Posted by Unknown on 10th Nov 2017

We had tried all the different kits before we used the Kwikwire kit
It was quickly apparent that their kit was the best
So much so that we became a dealer for them
We're proud to offer the KwikWire kits at Texas Scouts

It Works!

Posted by misskim on 6th Aug 2016

We were nervous about undertaking the wiring project on our 1959 Chevy Apache. The Kwikwire harness made it MUCH easier! Wiring diagrams, color coding, and labeling made the project much less intimidating. AND it is made in the USA! :-) We made one call to customer support and that too was a joy. Thank you!

Great value

I have not installed the harness yet. I can honestly say the quality looks top notch and the instruction manual very detailed. The soldered terminals in the fuse box are what attracted me to this harness over other manufactures. I also think it's a great value for the money.
