Step 1: Check Your Owner’s Manual

Before you start wiring your 1999 Chevy Blazer for towing, you need to check your owner’s manual to determine the maximum towing capacity of your vehicle. This will help you choose the right wiring kit for your needs.

It’s also important to ensure that your vehicle has a towing package installed. This package typically includes a trailer hitch, wiring harness, and other components that are necessary for towing.

Step 2: Remove the Tail Lights

The first step in wiring your 1999 Chevy Blazer for towing is to remove the tail lights. This will give you access to the wiring harness behind them.

To remove the tail lights, use a screwdriver to remove the screws that hold them in place. Once the screws are removed, gently pull the tail light assembly away from the vehicle to expose the wiring harness.

Step 3: Install the Wiring Harness

Now that you have access to the wiring harness, it’s time to install the wiring harness for your trailer. Most trailer wiring kits come with a pre-wired harness that connects directly to your vehicle’s wiring harness.

Follow the instructions that come with your trailer wiring kit to install the wiring harness. You’ll need to use wire connectors to connect the wiring harness to the tail lights and other components of your vehicle’s wiring system.

Step 4: Test the Wiring

Once the wiring harness is installed, it’s important to test it to make sure everything is working properly. Use a multimeter to test the wires for continuity and to verify that they are properly connected.

It’s also a good idea to test the trailer’s electrical system to ensure that it is working properly. Test the trailer’s brake lights, turn signals, and running lights to ensure that everything is functioning as it should.

Step 5: Secure the Wiring

Once you’ve confirmed that the wiring is working properly, it’s time to secure the wiring to prevent it from coming loose during travel. Use electrical tape and zip ties to secure the wiring to the vehicle’s frame and other components.
