Buying a quality automotive wiring harness is about asking the right questions. Before you buy any harness, make sure you know the answers to the questions below.
| Features | Hot Rod Wires® | Our Competitors |
|---|---|---|
| Made In The USA? | Most competitors source their harnesses from overseas. | |
| 100% Soldered Connections? | Most wiring harnesses are crimped only. It saves money, but reduces durability. | |
| Heavy-duty 12 Gauge Starter Wire? | Many harnesses use lighter gauge wire, which leads to hot start problems. | |
| OEM-Quality Made-in-the-USA Solid Copper Wiring? | Many competitors use a blend wire material for the wiring to cut costs. | |
| OEM-Quality Copper and Brass Terminals? | Many competitors use off-shore knock-offs made from aluminum or tin. | |
| Includes A Fusible Link? | A fusible link protects your entire electrical system, but many harnesses don't include it. | |
| Is The Harness Expandable? | Many competitors use the lightest gauge wiring possible for their 12-circuit harnesses. If you want to expand, you need to re-wire the harness. | |
| Compatible With Modern 100amp Alternator? | Many harnesses are only rated to 60 or 75amps, which means they won't accommodate a modern alternator. | |
| Heavy Gauge Copper Wire In Every Circuit? | Heavy gauge copper wire is expensive, but it minimizes resistance and ensures proper voltage across your system. | |
| Compatible With Halogen Headlights? | Many harnesses use light gauge wiring for the headlights that's insufficient for halogen bulbs. | |
| Built-in Theft Protection? | None. |

Testimonials
I’ve been doing business with Bill at Hot Rod Wires® for over 20 years.
They have wired my 32 Ford Roadster, 32 5-Window Coupe and the first tune port flathead. The 32 5-Window Coupe was the first electronic fuel injection in a street rod built in 1985 and was featured in Street Rodder Magazine October 1987.
I have been completely satisfied with all their work and everything is still running strong.
I would highly recommend Hot Rod Wires®!!!
