How to Bypass Ignition Switch

When it comes to bypassing your ignition switch, two major routes can be considered. Let’s take a look at them.

1. Jumpstarting 

Jumpstarting doesn’t only come in handy when your car battery has a low charge. Ignition switch issues can also be solved when you choose jump-starting as an alternate approach. To use this option, you need two things;

  • A portable jumper
  • Another vehicle (battery)

Before you even start, you must ensure both vehicles are turned off. Next, locate the ignition coil and battery of each vehicle. Following the last step, you need to connect the positive terminal of the ignition coil. 

Next, you need to detach the ignition switch from the solenoid and connect it to where the ignition switch attaches. After this process, electricity will be directly passed to your car dashboard via the starting solenoid.  

2. Hotwiring 

Hotwiring your car begins with locating the required wires to start your vehicle. These wires can be found below your steering wheel. After removing a plastic case-like covering beneath your steering wheel, you will find a set of wires.

In this process, you need to pay attention to three wires: the ignition, battery, and starter connector. Next, all you need to do is strip the ignition and battery wires and connect them. To start the engine, you must strip the starter wire and attach it to the battery wire. With these processes complete, your vehicle should start running.

This is simply replacing your ignition switch with a toggle switch. It ‘bypassing’ method provides a permanent and long-lasting solution to your ignition switch-related issues.

Research has proven that most car drivers prefer toggle switches to regular ignition switches. It is important to note that toggle switches are typically utilized in place of ignition switches. It is easier to make this switch for older model cars without computer-controlled engine management systems.
