Wiring Diagram for Plow Lights: A Comprehensive Guide

Winter brings with it a lot of challenges, and one of them is clearing snow from your sidewalks, driveways, and roads. If you own a plow, you know how important it is to have bright and efficient plow lights. These lights not only help you to see where you are plowing in the dark, but they also signal other drivers on the road. In this guide, we will provide you with a detailed wiring diagram for plow lights, including tables and FAQs to help you get started. So let’s dive in!

What are Plow Lights?

Plow lights are lighting systems that are installed on the front of snow plows. These lights illuminate the snow ahead of the plow, making it easier for the operator to see where they are going. Plow lights also make it easier for other drivers to see the plow, reducing the risk of accidents. There are various types of plow lights available in the market, but they all require a wiring system to function.

Types of Plow Light Wiring Systems

There are two main types of plow light wiring systems: Positive Ground and Negative Ground. Let’s take a look at each of these systems in detail.

Positive Ground Wiring System

In a Positive Ground Wiring System, the positive terminal of the battery is connected to the frame of the vehicle, and the negative terminal is connected to the lights. This type of system is commonly found in older vehicles and requires a slightly different wiring diagram than a Negative Ground Wiring System.

Components

The components required for a Positive Ground Wiring System include:

Component Description
Battery 12 Volt Positive Ground Battery
Plow Lights Two 12 Volt Plow Lights
Toggle Switch On/Off Toggle Switch
12 Gauge Wire Wiring for Lights and Toggle Switch
Fuses Two 15 Amp Fuses
Wiring Diagram

To wire a Positive Ground Wiring System, follow the diagram below:

Start by connecting the positive terminal of the battery to the frame of the vehicle. Then, run a 12 gauge wire from the positive terminal of the battery to the toggle switch. Connect one wire from each plow light to the toggle switch. Then, connect the other wire from each plow light to the negative terminal of the battery. Finally, insert a 15 amp fuse on each of the wires going to the lights.

Negative Ground Wiring System

In a Negative Ground Wiring System, the negative terminal of the battery is connected to the frame of the vehicle, and the positive terminal is connected to the lights. This type of system is commonly found in newer vehicles and requires a slightly different wiring diagram than a Positive Ground Wiring System.

Components

The components required for a Negative Ground Wiring System include:

Component Description
Battery 12 Volt Negative Ground Battery
Plow Lights Two 12 Volt Plow Lights
Toggle Switch On/Off Toggle Switch
12 Gauge Wire Wiring for Lights and Toggle Switch
Fuses Two 15 Amp Fuses
Wiring Diagram

To wire a Negative Ground Wiring System, follow the diagram below:

Start by connecting the negative terminal of the battery to the frame of the vehicle. Then, run a 12 gauge wire from the positive terminal of the battery to the toggle switch. Connect one wire from each plow light to the positive terminal of the battery. Then, connect the other wire from each plow light to the toggle switch. Finally, insert a 15 amp fuse on each of the wires going to the lights.

FAQs

1) How do I know if my vehicle has a Positive or Negative Ground Wiring System?

A: To determine whether your vehicle has a Positive or Negative Ground Wiring System, look at the battery terminals. If the negative cable is connected to the negative terminal, then you have a Negative Ground Wiring System. If the positive cable is connected to the negative terminal, then you have a Positive Ground Wiring System.

2) Can I use any type of plow light for my vehicle?

A: No, you cannot use any type of plow light for your vehicle. The plow lights you choose must be compatible with your vehicle’s electrical system. It is recommended to consult your vehicle’s manual or a professional to ensure you choose the right plow lights.

3) Do I need to ground my plow lights?

A: Yes, you need to ground your plow lights. Failure to ground your plow lights can result in electrical damage to your vehicle or even an electrical fire. Always follow the wiring diagram provided for your specific system to ensure proper grounding.

4) Can I install my plow lights myself?

A: Yes, you can install plow lights yourself if you are familiar with electrical systems and have the necessary tools. However, it is recommended to consult a professional if you are unsure or uncomfortable with the installation process.

5) What happens if my plow light fuse blows out?

A: If your plow light fuse blows out, it means the circuit has been overloaded or there is a short circuit. In either case, you need to replace the fuse with a new 15 amp fuse. However, if the fuse continues to blow out, it is recommended to consult a professional to diagnose and repair the issue.
