Building a race car from scratch is often easier than upgrading an existing vehicle, especially when it comes to installing engine sensors and gauges. If you want an accurate read on how your engine is operating, you need a quality motorsport wiring harness in Santa Rosa, CA. With so many different wires involved, it’s crucial that you buy from a company that uses materials and construction methods that are made to last. If even one wire is improperly soldered or spliced, your data analysis will be off—and it’s hard to narrow down which wire is underperforming.

Fine Line Imports offers a variety of motorsport grade wiring harnesses for your engine—shop online or call us today to learn more about our offerings.

What is a wiring harness?

A wiring harness is, at its most basic, a collection of electrical wires bound together, and they’re used in everything from computers and airplanes to race cars. Binding wires together with a durable material like electrical tape, rubber or vinyl serves to prevent loose wires from moving around the engine compartment. Less movement ensures that there is a lower likelihood that the wires will come loose, short out or be damaged by vibration, moisture and other adverse conditions.

Wiring harnesses in Santa Rosa, CA are often made by hand, grouping specific wires together; sleeves, clamps and cable ties are all methods of keeping the wires organized and protected. Sometimes this process can be partially automated, including cutting and stripping wires and adding terminals, but the majority of the construction needs to be done by hand.

The importance of quality construction

When you’re investing in a motorsport-grade wiring harness, quality construction should be your top priority. Here are some tips to make sure your harness is the best it can be:

• Connectors: Make sure that your company uses the right connectors for the job—consider the temperature, amperage through each contact, whether there will be moisture around the wiring and how many contacts you need.
• Soldering vs. splicing: Splicing is a superior way to connect wires—soldered wires can split under vibration. Ask your wiring harness company whether they solder or splice. If they solder, ask how they seal it—rubber and silicone can help support the wiring.
• Wiring and sleeving: Extremely high-quality wiring and sleeving techniques are called “milspec” or “military spec,” and can be used in vehicle wiring harnesses—if your seller uses these techniques, you’ll likely get a higher quality wire harness.
• Diagrams: Your harness should come with a detailed diagram of the wiring so that, in the event you have an issue, it can be easily repaired. If you’re making your own harness, don’t neglect this important step.
