Trailer Wiring Harness

Basic Trailer Wiring ( Auto Wiring Guide )
The trailer wiring harness, with a seven-pin connector, is at the rear of the vehicle and is tied to the vehicle’s frame. The harness requires the installation of a trailer connector, which is available through your dealer.

Use only a round, seven-wire connector with flat blade terminals meeting SAE J2863 specifications for proper electrical connectivity.

The seven-wire harness contains the following trailer circuits:

  • Yellow: Left Stop/Turn Signal
  • Green: Right Stop/Turn Signal
  • Brown: Tail/Parking Lamps
  • White: Trailer Ground
  • Red: Stop Lamp Supply Voltage
  • Black: Back Up Lamp Supply Voltage. Blue: Service Brakes

The fuse for the electric trailer brake circuit is in the engine compartment fuse block, but the wires may not be connected. They
should be connected by your dealer or a qualified service center. To control electric trailer brakes, a trailer brake controller needs to be installed on the vehicle by your dealer or a qualified service center. See electric brake control wiring provisions.

If a battery outside the vehicle is being charged, place the vehicle in Tow/Haul Mode. This will boost the vehicle system voltage and properly charge the battery. If the trailer is too light for Tow/Haul Mode, turn on the non-HID-only headlamps as a second way to boost the vehicle system voltage and charge the battery.

Wiring Solutions
When dealing with trailer wiring for a Chevrolet Blazer or any similar SUV, here are some tips to ensure a safe and effective connection:

  1. Use the Correct Wiring Harness:
    • Ensure that you use the appropriate wiring harness designed for your Blazer model and the specific trailer you are towing.
  2. Check the Vehicle’s Tow Capacity:
    • Verify the towing capacity of your Blazer and make sure it can handle the weight of the trailer and its contents.
  3. Inspect and Maintain Wiring Regularly:
    • Periodically check the condition of the trailer wiring, looking for any frayed wires, loose connections, or signs of wear. Replace any damaged components promptly.
  4. Connectors and Adapters:
    • Use high-quality connectors and adapters that match the trailer’s wiring system. Ensure a secure and weather-resistant connection.
  5. Secure Wiring Away from Moving Parts:
    • Route the wiring harness away from any moving parts, sharp edges, or hot surfaces. Use zip ties or clips to secure the wiring in a safe and organized manner.
  6. Utilize a Circuit Tester:
    • Before connecting the trailer, use a circuit tester to check that each wire is functioning correctly. This helps identify any wiring issues before hitting the road.
  7. Follow Color-Coding Standards:
    • Adhere to standard colour coding for trailer wiring (e.g., brown for running lights, yellow for left turn, green for right turn, etc.) to maintain consistency.
  8. Ground Connection:
    • Ensure a solid ground connection for the trailer wiring. Clean any corrosion from the ground point on both the vehicle and the trailer.
  9. Use Dielectric Grease:
    • Apply dielectric grease to connectors to protect against corrosion and ensure a secure electrical connection.
  10. Check Brake Lights and Turn Signals:
    • Verify that all trailer lights, including brake lights and turn signals, are working correctly before each trip.
  11. Adapt to Different Trailers:
    • If you tow different trailers with varying wiring configurations, consider using adapters to ensure compatibility.
  12. Waterproof Connections:
    • Use waterproof connectors and wrap connections in electrical tape or heat shrink tubing to protect against moisture, especially if you anticipate driving in rainy or wet conditions.
  13. Secure Loose Wiring:
    • Secure any excess or loose wiring to prevent it from dragging on the ground or getting caught in moving parts.

Trailer Lamps

Lighting Installation

Always check all trailer lamps are working at the beginning of each trip, and periodically on longer trips.

Turn Signals When Towing a Trailer
When properly connected, the trailer turn signals will illuminate to indicate the vehicle is turning, changing lanes, or stopping. When towing a trailer, the arrows on the instrument cluster will illuminate even if the trailer is not properly connected or the bulbs are burned out.

Tow/Haul Mode
For instructions on how to enter Tow/Haul Mode, see Driver Mode Control 0 206. Tow/Haul assists when pulling a heavy trailer or a large or heavy load. See Driver Mode Control 0 206. Tow/Haul Mode is designed to be most effective when the vehicle and trailer combined weight is at least 75% of the vehicle’s Gross Combined Weight Rating. (GCWR). See “Weight of the Trailer” under.

Trailer Towing

Tow/Haul Mode is most useful when towing a heavy trailer or arraying a large or heavy load:

  • Through rolling terrain.
  • In stop-and-go traffic.
  • In busy parking lots.
  • Operating the vehicle in Tow/Haul Mode when lightly loaded or not towing will not cause damage; however, it is not recommended and may result in unpleasant engine and transmission driving characteristics and reduced fuel economy.

Trailer Sway Control (TSC)
Vehicles with StabiliTrak/Electronic Stability Control (ESC) have a Trailer Sway Control (TSC) feature. Trailer sway is the unintended side-to-side motion of a trailer while towing. If the vehicle is towing a trailer and the TSC detects that sway is increasing, the vehicle brakes are selectively applied at each wheel, to help reduce excessive trailer sway. If equipped with the Integrated Trailer Brake Control (ITBC) system, and the trailer has an electric brake system, StabiliTrak/ESC may also apply the trailer brakes.Chevrolet Blazer 2023 Ride Control Systems User Guide 01

If TSC is enabled, the Traction Control System (TCS)/StabiliTrak light will flash on the instrument cluster. Reduce vehicle speed by gradually removing your foot from the accelerator. If trailer sway continues, StabiliTrak/ESC can reduce engine torque to help slow the vehicle. TSC will not function if StabiliTrak/ESC is turned off. See Traction Control/Electronic Stability Control 0 204.

Warning
Trailer sway can result in a crash and in serious injury or death, even if the vehicle is equipped with TSC. If the trailer begins to sway, reduce vehicle speed by gradually removing your foot from the accelerator. Then pull over to check the trailer and vehicle to help correct possible causes, including an improperly or overloaded trailer, unrestrained cargo, and improper trailer hitch. configuration, or improperly inflated or incorrect vehicle or trailer tires. See Towing Equipment 0 241 for trailer ratings and hitch setup recommendations.

Trailer Tires
Special Trailer (ST) tires differ from vehicle tyres. Trailer tyres are designed with stiff sidewalls to help prevent sway and to support heavy loads. These features can make it difficult to determine if the trailer tire pressures are low only based on a visual inspection. Always check all trailer tire pressures before each trip when the tyres are cool. Low trailer tire pressure is a leading cause of trailer tire blowouts. Trailer tyres deteriorate over time. The trailer tyre sidewall will show the week and year the tire was manufactured. Many trailer tyre manufacturers recommend replacing tires more than six years old. Overloading is another leading cause of trailer tyre blowouts. Never load your trailer with more weight than the tyres are designed to support. The load rating is on the trailer tyre sidewall. Always know the maximum speed rating for the trailer tyres before driving. This may be significantly lower than the vehicle tire speed rating. The speed rating may be on the trailer tire sidewall. If the speed rating is not shown, the default trailer tire speed rating is 105 km/h (65 mph).
