Neutral Safety Switch Bypass [Meaning & Common Problems]

If you own a car with an automatic transmission, then you’re probably familiar with the Neutral Safety Switch.

This component acts as a safety measure that prevents the engine from starting unless the transmission is in “Park” or “Neutral.” But what if you want to bypass this switch? Well, that’s what we’ll be discussing today.

As car enthusiasts, we always look for ways to improve our vehicles and make them more convenient to use. Bypassing the Neutral Safety Switch offers just that. It allows the engine to start even if the transmission is not in “Park” or “Neutral.” 

This can come in handy for racing purposes or vehicles with a damaged Neutral Safety Switch. It also makes it easier to start the engine while towing or doing other tasks that require the engine to be running while the transmission is in gear.

We’ll go over what the Neutral Safety Switch Bypass is, why you might want to do it, the steps to bypass it, and the safety precautions to take.

What is a Neutral Safety Switch Bypass?

A Neutral Safety Switch Bypass is a modification that allows the engine to start even if the transmission is not in “Park” or “Neutral.” This modification is often done for racing purposes or for vehicles that have a damaged Neutral Safety Switch. 

By bypassing the switch, the vehicle becomes more versatile and convenient to start, especially when towing or doing other tasks that require the engine to be running while the transmission is in gear.

Steps to Bypass Neutral Safety Switch

Bypassing the Neutral Safety Switch is a relatively simple process that can be done with a few basic tools. The tools you’ll need include a wiring diagram for your vehicle, wire cutters, and a soldering iron.

The detailed procedure for bypassing the Neutral Safety Switch varies depending on the make and model of your vehicle, but the general steps are as follows:

1. Gather Tools and Supplies

Before you start the bypass process, make sure you have everything you need to complete the job. You’ll need a wiring diagram for your vehicle, a multimeter, electrical tape, and a few other tools. Having these supplies on hand will make the process smoother and faster.

2. Locate the Neutral Safety Switch

Once you have your tools and supplies, it’s time to locate the Neutral Safety Switch. This component is typically found near the shifter assembly and is connected to the transmission.

To ensure you’re working on the right part, consult your vehicle’s wiring diagram. This will give you a clear picture of the location and the wires that connect to the Neutral Safety Switch.

3. Test the Neutral Safety Switch

Before you disconnect the Neutral Safety Switch, it’s a good idea to test it. This will ensure that you’re bypassing the right component and that it’s the problem.

Use your multimeter to test the switch. If the multimeter indicates that the Neutral Safety Switch is faulty, then you’re ready to proceed with the bypass.

4. Disconnect the Neutral Safety Switch

With the switch confirmed as faulty, it’s time to disconnect it. Cut the wires going to the switch and use electrical tape to insulate the ends. This will prevent any electrical current from flowing through the Neutral Safety Switch.

5. Connect the Wires

With the Neutral Safety Switch disconnected, it’s time to connect the wires. Splice the wires together and use electrical tape to secure the connection.

Make sure the connection is secure and that there’s no chance of a short circuit. This is an important step, as a short circuit could cause damage to your vehicle’s electrical system.

6. Test the Bypass

Finally, it’s time to test the bypass. Start the engine and make sure it runs smoothly. If everything is working correctly, then you’re done! Your vehicle should now start even if the transmission is not in “Park” or “Neutral.”

Common Problems with Neutral Safety Switch Bypass

While bypassing the Neutral Safety Switch can offer many benefits, it can also cause some problems. Some common issues include:

  1. failure to start in gear
  2. loss of power 
  3. malfunctioning transmission.

The cause of these problems is often a result of a poor connection between the two wires or a short circuit caused by the bypass. To avoid these issues, it’s essential to follow the steps carefully and ensure a proper connection between the two wires.

Can You Bypass the Neutral Safety Switch?

Yes, it is possible to bypass the neutral safety switch in a vehicle. The process involves disconnecting the switch and connecting the wires connected to the switch, allowing the vehicle to start even if the transmission is not in “Park” or “Neutral.” 

However, it’s important to note that bypassing the neutral safety switch can potentially be dangerous. It could cause the vehicle to suddenly move forward or backward, putting the driver and others at risk.

We recommend that you do this when testing the neutral safety switch only. Bypassing the switch may seem like a quick and easy solution, but it’s not safe and could lead to further problems in the future.

How Do You Start a Car Without Neutral Safety Switch?

To start your car without a neutral safety switch requires you to ensure the transmission is on neutral. Simply shift the gear lever into the neutral position.

Then, turn the key to the “On” position and hit the starter to fire up the engine.

It is important to nor starting a car without a neutral safety switch can void the warranty on your vehicle. So, if your neutral safety switch isn’t working properly, it’s better to get it repaired or replaced by a professional. 

FAQ on Neutral Safety Switch Bypass 

Can I Drive Without a Neutral Safety Switch?

Yes, you can drive a vehicle without a neutral safety switch. However, it’s not recommended. Bypassing the switch removes this safety feature, which can be dangerous if the car were to start while it is in gear.
