What is Automotive Wiring?

Automotive electrical wiring connects your car battery to essential accessories like the windshield wipers, the headlights, brake lights, car horn, radio, and any other electronically run systems. There are many different kinds of wires to fit the needs of specific vehicles or sections of cars. You can replace one cable, or reroute the entire system of the vehicle.

Here is a list of the most common type of wiring:

  • Automotive cross-link wire —used to connect circuit protection devices and wire connectors to the engine
  • Primary GPT wire — another standard circuit wire that can take extreme heat
  • Brake cable — the wire that initiates the braking sequence in cars with cable-pull brakes
  • Battery cable — this cable connects the battery system directly to the car’s electrical system
  • Marine-grade wire — used to connect the electrical systems on boats
  • Service cord — electrical wiring typically used with industrial machineries like tractors, motors, and lighting
  • Shielded cable — wiring used with electric and hybrid vehicles
  • Trailer cable — provides electricity to the brake lights on an attached trailer

Even amongst this great variety, there are still significant differences in the function within each wire category. Let us take a closer look at some of these details, so we are aware of what types of products Painless wiring offers.

Typically companies either make automotive wiring out of copper or aluminum. Copper is generally the superior product since it does not rust as quickly, it conducts electricity well, and it is flexible. However, it is much more expensive than aluminum. Aluminum both weighs and costs less, but you will find that it needs replacing much more frequently. Wiring usually also mentions the total amount of electricity that flows through them, also known as the amperage of the tubing.

Other factors, like gauge, determine where the wire will go. This indicator essentially is a measure of thickness and cables with the lowest gauge are usually the ones that stretch the furthest regarding length. There are also two types of wire connections you should be familiar with: soldered, which use terminals for their electric connections, and solderless, which do not make contact. Wires also may come in different colors. This variety of colors is usually to help you identify which wire is which when cross-connections occur.

Painless Performance Products also has a customer service that many of the larger, mass-produced companies seem to lack, The company genuinely seems to care about maximizing the efficiency of their customers cars and vehicles.

Painless wiring boasts a proud history of award-winning products: the SEMA Industry Awards Banquet in Las Vegas awarded them over ten different awards over the years. This proven quality may make the brand a little more expensive than some competitors, but it is generally worth it.

How Much Does Painless Performance Products Wiring Usually Cost?

Since Painless Performance Products offer a veritable catalog of wiring solutions –all at different costs — so we decided to look at the pricing on their three most popular wiring: specifically the 30802 High Beam Headlight Relay Kit, the 30815 Hdlt Rel Conv Harn, and the 70107 Cirkit Boss Kit Seven Circuit. This sampling of products gives you a good feel for how much the standard product costs. However, more rare wiring systems (i.e., vintage cars or racing cars) will likely cost more — probably upward of two hundred to five hundred dollars.

What Do Most People Think About Painless Performance Products Wiring?

Though everyone typically admits that the price of Painless wiring is a little on the expensive side, most users agree the quality is almost unmatched. Painless Performance Products are all easy to install and they are better than many leading brands. They make their wires easy for the user to identify with bright colors and quality materials. Headlights relays help car lights shine brighter than ever, and the circuit kits ensure connection longevity for each section it attaches within the vehicle.

However, Painless wires do not shine too bright like some other factor installs. Some people have an issue with their wiring working too well, meaning it overloads and trips the systems. Painless wires will get rid of the flicker associated with this issue.

The Hella relays included with most wiring kits are top notch — far beyond the grade and quality that most auto-parts stores can offer. A combined wiring system between these two relays ensures that no wire becomes wasted when you work on your car. The lack of wire splicing is also a refreshing break from other automotive wiring kits. All in all, these wiring packages carry all the cable you will need for a passenger car, truck, or another automotive vehicle.

Some people do not prefer the constant hot fuses. The fuses remain on always which may drain the batteries of some vehicles — especially older models of cells. It is also a bit inconvenient that the Painless wiring kits do not come with a ground post connected to the local fuse block. The screws included in the packages also often do not fit the specific part of the car that needs screw replacements. Some users also had problems attaching headlamp connector meetings through the body of their vehicle, particularly with Jeep models.

How Does Painless Performance Products Wiring Compare to Other Automotive Wiring Brands?

In this section, we compare Painless Performance Products with some other top sellers of automotive wiring. Specifically, we look at the companies Waytek Wire, Del City and Heyco. By looking at Painless Performance Products’ competition, we hope to tease out what areas Painless wire excels in and what areas it may not be as suitable.

Waytek Wire

Waytek Wire offers individual wires and systems for your automotive electric system. Wiring is cheap — usually, around fifty cents per foot and they offer a wide selection of gauges, styles, and colors.

This option may be preferable to buying an expensive Painless wiring kit if you only need to replace one faulty wire. Or, if you feel adventurous, you can make your system using the individual parts and pieces. But keep in mind that this process can get confusing quickly — especially when the wires are not appropriately colored.

Del City

Del City offers a similar setup to Waytek Wire — over one thousand different types of wires are available for individual purchase instead of prepackaged kits. The company provides primary wire gauge sizes between twenty and eight.

However, Del City’s cable is of a slightly higher quality than Waytek Wire thanks to its copper wire strand in PVC insulation. These wires will not quit on you as quickly as Waytek wires, but they do cost a little more — around seventy cents per foot.

While Heyco does not specialize in automotive wiring, they still offer a pretty great product for their low price. In particular, the terminals and relays that Heyco offers are much better quality than Del City and Waytek wire. But, if you are only looking for cable,e then you have a better chance of going with one of the other companies.

Things You Should Keep In Mind When Wiring Your Vehicle

Before wiring accessories or replacing the automotive wires on your vehicle, you should always have a plan before proceeding. If you do not, you can quickly become lost trying to find your way through the innards of your vehicle. Look online for some general electrical systems diagrams.

You will also need the right tools before you proceed. You will require wire strippers for stripping insulation, wire crimpers for installing solderless connectors, and soldering iron for splicing wire connections. Generally, this also includes things like a wire brush, for scraping away rust, grease, and oil from the battery and internal parts, a voltmeter for measuring the conductivity of the wire, a shrinking tube for insulating and exterior connections, and a test light for testing the power levels within the circuit.

When setting up your wiring system, make sure you place your power source in a central location like the center console or the glove box. Then, wire everything from the power source to its prime location or accessory. As we mentioned before, you need to label your wires. Otherwise, they can easily get mixed up. If your cables are not colored, then mark them with a sticker or a pen.
