What Are The Steps To Install Blind Spot Detection Systems?

The very first question that will pop into your mind after the purchase is how to install a blind spot monitoring system? After all, you want your product to work at an exceptional level, right? Well, we have a detailed answer to your query!

The steps to install blind spot detection systems vary with the type. To add on blind spot monitors is not always an easy task for the driver. However, most blind spot monitoring installation is easier than supposed. Significantly, the blind spot system with basic functions is much more lenient to install and maintain.

Some blind spot detection systems have a complex design. Therefore, the wiring connection of these systems is also complicated. The steps to install a blind spot warning system depend on the part included in the package. However, the general steps are the same. By following these, you can install blind spot detection systems correctly.

  1. Radar Installation
  2. Wire connection
  3. Alarm system installation
  4. Control box installation (if included inside the package)

Radar Installation:

The very first step to install blind spot detection systems is the mounting of radar. Some of the designs have one, while some include two radars. Mounting a single radar is easier.

However, there are several guidelines that you must keep in mind while installing blind spot detection radar. All of those guidelines are as follows:


  • Make sure you install the radar at its specific position. Some sensors go on the back, while some to the side. So, it is better to know the ideal position of the radar.
  • If the blind spot warning system has two radars, observe if the manufacturer specifically marked the left and right radars. If yes, then install them accordingly. If there isn’t any, mark the radar and its wire harness yourself. It will help you distinguish right and left radar wire connections easily.
  • Ensure the radar sensor’s angle is the same as mentioned in the manual.
  • Some packages include a protractor. Measure the angle between radar and the body with that.
  • Measure the angle that radar makes with the ground. Because that directly affects the alarm area.
  • Make sure you do not block the radar with any metal object.
  • Make sure that you are not mounting the radar in an inverted position


Same as the guidelines, the steps to install blind spot detection systems are also of great importance. Therefore, every driver must follow these strictly.

  1. Check whether the radar is for the right or left side. If there isn’t any mark, install it on either side.
  2. Attach the double-sided sticker or the bracket provided in the package for mounting the radar sensor.
  3. After bracket attachment, mount the radars on it. In the case of stickers. Just peel the cover and stick the radar to the surface.
  4. Now adjust the angle with the help of a protractor given in the blind spot monitor kit.
  5. Once you are sure of the accurate angle, hold the radar in place and tighten the screws of the bracket.

General steps to install blind spot detection systems are the same as these. Although keep in mind that some firms have different procedures of install the blind spot radar sensor. The installation procedure depends on the vehicle type and the package variant. So, it is better to look inside the manual if the steps differ from these.

Wire Connection:

Several wires remain the same throughout different packages. For instance, the radar wire harness, power cord, power supply harness, and indicator wire harness stay the same. However, some blind spot sensor systems have extra pairs of wires, such as buzzer wire harness and control box connection wires.

Manufacturers color their connection wires. So this makes the overall procedure to install blind spot detection systems easier. Yet, some complex wiring connection procedures confuse the driver and cause irreversible errors. The general steps of wire connection for a blind spot sensor system are as follows:

  • The power supply has sub wires of different colors. The first step is to connect their terminals to the specific connection points.
  • The grounding power supply color is mostly black. Connect it to the negative pole of the vehicle body or ground it.
  • Connect the yellow wire of the power supply with the vehicle’s power source (mostly ACC 12V).
  • Connect the red wire of the power supply to the same power source.
  • Connect the indicator wire extension from the main wire harness to the respective side indicators.
  • In some blind spot systems, you can extend the sensor cable connection by a 6P sensor wire.
  • Now attach both short and long radar lines to the extension of the sensor cable. Moreover, connect the white and yellow wires from the sensor cable to the left and right turn lamps, respectively.

Start the engine and check whether the system is working properly. If it is not, recheck the wire connection. If the failure continues, consult your manual if the installation guide is any different. If all of this goes in vain, call your blind spot system operator and ask for help.

Alarm System Installation:

The alarm system of most blind spot monitors includes a buzzer and a pair of warning lights. Both of these parts are in-vehicle installed. Mounting both of these is pretty easy and fast.

The drivers install blind spot detection systems and warning lights at a position that they easily see. The ideal position is the lower window pillar between the dashboard and side mirror. Use the double-sided stickers for blind spot indicator installation that are present inside the kit.

For the buzzer, use adhesive glue or stickers. However, some buzzers come with a mounting pad and screws. Install blind spot detection systems buzzer in front of the dashboard near the driver’s seat so that driver can hear it easily.

All the alarm equipment of the cars is in-vehicle. However, things take a turn for motorcycles. Motorcycle alarming equipment like lights is always present in the harsh environmental conditions. Extreme sunlight, water during rain, and dust can affect their efficiency. So, install those in a place where ecological conditions affect them the least.

Control Box Installation:

Some blind spot sensor systems come with pre-equipped control boxes. These boxes bring extra functions. For instance, increasing, decreasing, or muting the volume of the buzzer, changing the intensity and sequence of the flashing lights, etc.

Connect all the wire harnesses to specific terminals to install blind spot detection systems’ control box. Attach the buzzer and indicator light extension harness to their particular terminal. The final step is to give a power supply by connecting it to the power source or power cord.

Is It Easy To Install Blind Spot Detection Systems?

Both Yes And No! Installing blind spot detection system is easier for the types with less complicated working mechanisms. However, it is really complex and difficult for high-end or top-tier detection systems.

Take a 24GHz single warning indicator light blind spot monitoring system as an example. Just by connecting some pair of wires, you can install blind spot detection systems. So, just in minutes, general vehicle drivers can install the blind view monitor themselves.

On the other hand, the same person can’t install a 77GHz dual radar with a control box. The advanced alarm system and additional control box make it even more difficult. For that reason, only a person with exceptional expertise in the field can install it.

Moreover, you must never install blind spot detection systems that have cameras and screen systems all by yourself. Due to its complex wiring and longer procedure, you’re guaranteed to make a mistake. For that reason, most companies give free or discounted installation help with the purchase. Even if you don’t get the assistance, try to look for a suitable technical worker.

Are the steps to install blind spot detection systems The Same For Every Variant?

No, It is not! Every firm designs its products according to the vehicle type and specifications. Therefore, there are major changes in all the blind spot systems. The steps to install blind spot detection systems for cars won’t be the same as a truck blind spot system. Same as that, the motorcycle blind spot system will have a different procedure.

However, to a basic and general overview, you can say the building steps are the same for every system. All the designs have radar and an alarming system. Along with that, every system needs a power supply. So attaching these wires and connecting of respective wire harnesses are the same steps in every variant. For that reason, we can say to some extent, the basic steps to install blind spot detection systems are the same.

Are There Any Ways To Install Blind Spot Detection Systems Other Than Self Installation?

Yes, there is! But you need to judge whether you need that or not. If you couldn’t install blind spot detection systems perfectly, it would be best to call for help. You can either contact your blind spot monitoring system firm or a private technical worker.

The blind spot system manufacturers mostly give free installation with the purchase of the product. However, if you cannot get free installation, it is better to pay for it. A perfectly installed blind spot system ensures the absolute functioning of the equipment.

What Is The Blind Spot Detection System Installation Cost?

There isn’t any specific price to install blind spot detection systems. It depends on the complexity of the procedure. The more difficult the process is, the more expensive will be the cost of blind spot system installation.

The blind spots system installation cost is 100 $ to 250 $. The basic blind spot monitoring system installation procedure does not need any additional help. So, that installation is free of cost and done by drivers themselves. However, if one is unwilling to install blind spot detection systems with basic complications, the ideal cost of its installation is 100 $ to 150 $.

Self Installation Or Paid Installation; Which One Is Better?

Both installation methods have their own benefits and drawbacks. People consider the steps to install blind spot detection systems rocket science. However, that is not the whole truth. Both these installation routines are ideal. Although, numerous conditions make one superior to the other. We’ll discuss both of these in detail below.

Self Installation:

The drivers conduct these types of installations all by themselves. It does not include any intense technical procedure. Simple connection and arrangement of wires can ensure error-free installation. The self-installation is ideal for the following systems.

  • Single radar systems
  • Basic alarm systems
  • Motorcycle blind spot systems

However, along with the benefits of self-installation comes numerous drawbacks. Some of the primary advantages and disadvantages are as follows:

Advantages Of Self Installation:

  • It is easy to conduct.
  • It is of no financial cost as drivers can do everything all by themselves.
  • It helps to install blind spot detection systems with minute effort.

Disadvantages Of Self Installation:

  • It is not reliable.
  • There are higher risks of errors.
  • It is time-consuming for drivers.
  • It can cause irreversible errors while driving if installed with carelessness. So, it poses risks to the car and the driver.

Paid Installation:

Paid installation can be of two origins. You can either hire private technical personnel to install blind spot detection systems or get the service directly from the firm where you got the product. You can use this blind spot monitor installation procedure on all types of designs, from basic to advanced.

However, you must hire a professional technical worker for screen and camera blind spot systems. These systems are the most complex and confusing to use and install. Paid installation is suitable for these products.

  • Systems with advanced alarm equipment (both buzzer and warning lights)
  • Blind spot system with cameras and screens.
  • Blind spot system with a control box

Same as the prescribed category, this method also has its own benefits and drawbacks. Some of these are as follows.

Advantages Of Paid Installation:

  • It is much more reliable compared to the self-installation method.
  • It removes any risks of errors.
  • It ensures the perfect blind spot system installation. For that reason, any misconnection chances reduce to a great extent. It saves the battery and wire connection damage.
  • Experienced technical personnel performs this task. Therefore, the installation process is less time-consuming.

Disadvantages Of Paid Installation:

The only drawback of this installation process is its price. It is overpriced for a basic installation procedure. However, for advanced systems, it becomes a necessity. Therefore, it suits people using top-tier or flagship blind spot monitors.

My final thoughts about the choice are that every blind spot system does not need paid installation. Despite being better, spending extra dimes for work that you can do all by yourself is not a wise decision.

However, when paid installation becomes necessary, It’s not wise to save some pennies and install blind spot detection systems themselves. The reason is the increased risk due to your inexperienced installation skill. So, If the paid installation can promise you a perfectly installed blind spot system, It can also ensure your safety.

OYI company's factory areaConclusion:

The procedure to install blind spot detection systems is both easier for basic and difficult for advanced techniques. However, one can always take help from paid sources for a perfect and correctly installed blind spot monitor.

A blind spot system can only work if every part is precisely in its place. So, the driver must correctly install blind spot detection systems for every aspect. If they are looking for a blind spot system with supreme functionality, they must pay great attention to smaller installation details. Some firms want their products to work at the best level possible. So, they offer free installation by themselves. Therefore, try to buy from a firm that values the customer’s needs
