will walk you through the key aspects of the Tekonsha 90155 Primus electric brake

controller manual, helping you get the most out of your device and ensuring a smooth,

safe towing ride.

Understanding the Tekonsha 90155 Primus Electric Brake

Controller

The Tekonsha 90155 Primus is an electric brake controller designed to provide

proportional braking for trailers equipped with electric brakes. This means it senses the

vehicle’s braking force and applies the trailer brakes accordingly, resulting in balanced

and responsive stopping power.

What Makes the Tekonsha 90155 Unique?

One of the standout features highlighted in the Tekonsha 90155 Primus electric brake

controller manual is its proportional braking technology. Unlike time-delayed controllers,

which apply a fixed amount of power for a preset time, the Tekonsha Primus senses the

deceleration of the tow vehicle and applies the trailer brakes in proportion. This greatly

reduces wear and tear on the trailer brakes and improves overall control.

Additionally, the manual points out the simple, user-friendly interface of the 90155 model.

It includes a manual override lever, allowing drivers to apply trailer brakes independently

without pressing the vehicle brake pedal—useful for controlling trailer sway or during

maneuvers.

Installation Tips from the Tekonsha 90155 Primus Electric Brake

Controller Manual

Installing the Tekonsha 90155 Primus is a task many DIY enthusiasts can tackle, especially

with the manual’s detailed instructions. Proper installation is critical to ensure the brake

controller functions correctly and safely.

Choosing the Right Location

The manual recommends mounting the controller within easy reach of the driver, but

without obstructing access to other controls or vehicle operation. A common spot is under

the dashboard, to the left of the steering column, but this depends on your vehicle’s

layout.

Wiring and Connections

The Tekonsha 90155 Primus electric brake controller manual provides wiring diagrams

that illustrate how to connect the unit to your vehicle’s electrical system. The key wires

typically include:

Power wire (usually red): Connects to a 12-volt ignition source that provides

1.

power when the vehicle is on.

Ground wire (black): Ensures proper grounding to the vehicle chassis.

2.

Brake signal wire (blue): Connects to the trailer brake output or brake switch.

3.

Output wire (white): Connects to the trailer brake wiring harness.

4.

Following the manual’s instructions carefully is vital to prevent electrical issues or brake

failure. It also recommends testing the system after installation to verify that the trailer

brakes respond correctly.

Operating the Tekonsha 90155 Primus: Insights from the Manual

Once installed, understanding how to operate your Tekonsha 90155 Primus brake

controller enhances your towing safety and comfort.

Adjusting the Braking Power

The manual explains how to adjust the gain or braking power, which controls the amount

of current sent to the trailer brakes. This adjustment is crucial because too little braking

power can cause the trailer to push the tow vehicle, while too much can lock the trailer

wheels and cause skidding.

Many users find it helpful to start with a moderate setting and then adjust based on the

trailer’s weight and road conditions. The Primus 90155 features a simple dial for gain

adjustment, making it easy to fine-tune on the go.

Using the Manual Override

The manual override lever is a handy feature when you need to apply trailer brakes

independently. For example, if your trailer is swaying or you want to slow it down without

applying the vehicle brakes, you can use this lever to engage the trailer brakes manually.

According to the Tekonsha 90155 Primus electric brake controller manual, practicing the

use of the manual override in a safe environment before hitting the road is a smart idea

so you become comfortable with its responsiveness.

Troubleshooting Common Issues with the Tekonsha 90155

Primus

Even with reliable models like the Tekonsha 90155, occasional issues may arise. The

manual is a valuable resource for diagnosing and fixing these problems.

No Power to the Controller

If the brake controller isn’t powering on, the manual suggests checking the power source

and fuses first. Loose or corroded ground connections can also cause power issues, so

verifying the ground wire’s integrity is essential.

Trailer Brakes Not Engaging

When trailer brakes fail to engage, the manual guides you to inspect the brake output

wire and trailer connector for damage or poor connections. Testing the brake magnets on

the trailer itself can also help identify where the problem lies.

Inconsistent or Jerky Braking

If braking feels uneven, the manual recommends checking the gain settings and ensuring

the controller is properly mounted and aligned. Since the Primus 90155 is a proportional

controller, it relies on sensing deceleration accurately, so a secure installation is critical.

Why the Tekonsha 90155 Primus Remains a Top Choice

The continued popularity of the Tekonsha 90155 Primus electric brake controller comes

down to its blend of simplicity, reliability, and effective braking performance. The manual

highlights features like:

Compact design that fits neatly in most vehicle interiors

1.

Easy installation with clear wiring instructions

2.

Proportional braking technology for smooth and safe stops

3.

Manual override for added control in tricky situations

4.

Compatibility with a wide range of trailers and tow vehicles

5.

These strengths make it a go-to option for many towing enthusiasts who value safety

without complexity.

Additional Tips for Maximizing Your Tekonsha 90155 Primus

Experience

Beyond what the manual covers, there are a few practical tips to keep in mind:

Regularly inspect your trailer’s brake system to ensure magnets, wiring, and

1.

brake shoes are in good condition.

Periodically test the brake controller to confirm it responds correctly, especially

2.

before long trips.

Adjust the gain setting based on load changes—a lightly loaded trailer

3.

requires less braking power than a fully loaded one.

Keep the controller clean and free of dust to maintain good contact and

4.

prevent malfunction.

By combining these tips with the guidance in the Tekonsha 90155 Primus electric brake

controller manual, you can enjoy a safer and more confident towing experience.
