Why I Believe a 7 Pin Trailer Harness is Essential

As someone who has spent a significant amount of time hauling trailers, I can confidently say that a 7 pin trailer harness is absolutely necessary. This type of wiring system allows for the safe and efficient transport of all types of trailers, from small utility trailers to large RVs. Here are a few reasons why I believe every trailer owner should have a 7 pin harness:

1. Provides Power to All Trailer Lights
The most obvious reason for needing a 7 pin harness is that it provides power to all the lights on your trailer. This includes brake lights, turn signals, and running lights. Without this wiring system, you would not be able to safely signal your intentions while driving or properly illuminate your trailer at night.

2. Ensures Proper Grounding
In addition to powering the lights, a 7 pin harness also ensures proper grounding for your trailer’s electrical system. This is crucial for maintaining reliable and consistent functioning of all electrical components on the trailer. Improper grounding can lead to flickering or malfunctioning lights, which can be dangerous while on the road.

3. Allows for Electric Brake Control

My Buying Guide on ‘7 Pin Trailer Harness’

As someone who loves to travel and explore new places, I have always found trailers to be a convenient and practical option for road trips. However, when it comes to connecting my trailer to my vehicle, having a reliable and functional wiring system is crucial. This is where a 7 pin trailer harness comes in. After going through several options and conducting thorough research, I have put together this buying guide for those looking to purchase a 7 pin trailer harness.

What is a 7 Pin Trailer Harness?

A 7 pin trailer harness is an electrical wiring system that connects the lighting and braking systems of a trailer to the towing vehicle. It consists of seven pins or prongs that are used for different functions such as brake lights, turn signals, and electric brakes.

Consider Your Towing Vehicle

Before purchasing a 7 pin trailer harness, it is essential to consider the type of towing vehicle you have. Different vehicles may require different types of connectors or adapters for the wiring system to work correctly. Make sure to check your vehicle’s owner’s manual or consult with a professional mechanic before making a purchase.

Quality of Materials

When it comes to any electrical wiring system, the quality of materials used plays a significant role in its performance and durability. Look for harnesses made from high-quality materials such as copper wires and weather-resistant insulation. These will ensure that your wiring system can withstand harsh weather conditions and frequent use without deteriorating.

Number of Pins

As mentioned earlier, 7 pin trailer harnesses come with seven pins or prongs that serve different functions. However, not all trailers require all seven pins. It is essential to determine which pins you need based on your trailer’s lighting and braking systems before making a purchase. This will prevent you from overspending on unnecessary pins.

Length of Wiring

The length of the wiring included in the harness is another crucial factor to consider. Make sure to measure the distance between your towing vehicle’s hitch and the trailer’s connection point before purchasing a harness. It is always better to have extra length than not enough as it can cause strain on the wires.

Compatibility with RVs

If you own an RV or are considering purchasing one in the future, make sure to check if the 7 pin trailer harness you are interested in is compatible with RVs as well. This will save you from having to purchase separate wiring systems for your RV and other trailers.

Price Range

The price range for 7 pin trailer harnesses can vary significantly depending on various factors such as brand, quality, number of pins, etc. It is essential to set a budget beforehand and compare prices from different brands before making a decision.

In conclusion, investing in a good quality 7 pin trailer harness is crucial for safe and hassle-free towing experiences. By considering factors such as compatibility with your towing vehicle, quality of materials used, number of pins required, length of wiring, compatibility with RVs, and price range; you can find the perfect wiring system that meets your needs and budget.
