If you want to know how to perform the wiring of the ignition switch, regardless of your vehicle or the switch type, read on to learn the precise steps!

How To Know What Wires Go to an Ignition Switch?

To know what wires go to an ignition switch, you only have to remember these four wires that go into your vehicle’s switch: BATT (battery), IGN (ignition input), ST (starter), and ACC (accessory). These wires may come in different colors, so consult your manual to be sure.

How Can You Wire a Push-Button Ignition Switch?

You can wire a push-button ignition switch by turning off the engine and then locating the connected wires. You need to connect each wire from the switch to its respective terminal, as determined by the names written on them, and you are done.

Make sure to wear protective materials such as gloves while working on your vehicle to avoid any untoward accidents.

1. Turning off the Engine

The wiring for any ignition switch will generally depend on the vehicle model and type, but if you need to wire a push-button ignition switch, then the primary thing you need to do is park your car, making sure it is not a steep lane. You must ensure the engine is off once you have parked on level ground.

2. Locating the Wires

Once you have safely turned off the car engine and parked your vehicle, you must head over to the ignition switch and check the back. This is where you should be able to see the switch’s wires and the four different terminals connected to the ignition switch.

Locating Ignition Switch Wires

While it would be good to find the owner’s manual to see what each terminal stands for, generally, ACC stands for “accessory” and BATT for “battery.” On the other hand, IGN stands for “ignition,” and ST usually stands for “start.”

3. Disconnecting Terminals

After you have managed to successfully locate all the different cables that make up the complicated wiring, you will then need to go ahead and disconnect the linked battery terminal. To do this effectively, it would be ideal to first get your hands on a wrench or any similar tool.

Once you have the wrench, you can then proceed to disconnect the terminals, both positive and negative. While you are doing this, you must be very careful and ensure that you can prevent the negative terminal from having any contact with the other terminals.

4. Removing the Wheel Trims

Now that you have disconnected the negative and positive terminals of the battery, the next thing you need to do is remove the trims around the car’s steering wheel. If you want to remove them effectively, the easiest thing you can do is pull them right off.

You will also remove the plastic clips in place, so get the proper tools to help you get rid of all kinds of screws and bolts holding the clips in place. Once you have removed the plastic clips and the wheel trims, you need to ensure that they are put in a safe location where they have zero chances of being misplaced or damaged.

5. Accessing the Steering Column

Suppose you are wondering why you must remove the plastic slips and the trims from your car’s steering wheel. In that instance, you should know that this step is essential as it allows better access to the steering column where the ignition switch is placed.

Accessing Car Steering Column

If this is your very first encounter with such a switch, it might be a little complicated to know where the different components are. In that case, getting your hands on a detailed diagram of the ignition switch and its wiring would be an excellent idea. This will allow you to carry out the process faster and more efficiently.

6. Accessing the Ignition Switch

You must ensure proper access to the ignition switch after getting past the wheel and directly to the steering column. To accomplish this, remove the cover that is placed over the ignition module. It would be important to get your hands on a screwdriver at this stage, as you will need to use this tool to press down on the visible hooks and the release mechanism.

7. Getting to the Release Pin

Next, you have to get your car keys and place them in the slot for ignition. Once you have finished this, you will need to change their position until they are in the “Accessory” mode, which will give you the ability to access the ignition module and its release mechanism.

In the unfortunate scenario of not being able to find your car keys, you still have the option of using a screwdriver, preferably a flathead one. You can then use this tool to press down on the release pin located within the hole of the visible ignition module but take care not to be rash, or the sensitive pins could break.

8. Pulling the Release Pin

Once you have ensured that previous steps have been followed with care and accuracy, you next must let go of the pin that you had been pressing down. This pin is responsible for securing the ignition switch, and you must pull it out of its assigned position very carefully.

Remember that if you are careful while handling it and do it right away, the pin won’t give you any trouble, and you should be able to pull it out without putting in much effort. On the other hand, if it seems stuck and does not come out easily, try again and remain gentle while releasing it. Hopefully, it should come out effortlessly in no time.

9. Inspecting

After taking out the pin, you must get your hands on a small torch or a test light. Using this will allow you to assess the system for any signs of damage. If something is wrong with it, it would be a good idea to repair it immediately.

If you can’t do this alone, seeing a mechanic immediately would be best. On the other hand, you can also rebuild it or simply buy a new version of the component.

10. Checking for the Right Wires

While ensuring that you are not rash with anything in any way, you will need to see whether any wires link the power terminals of your car battery to the ignition switch. If you don’t know what to look for, you should know that the power terminal you are looking for is usually red.

Checking for Right Ignition Switch Wires

Now you will need to fix the cable attached to the end of the battery terminal, and once you are done and dusted, you will need to secure it firmly into place. To do this, getting your hands on a functional multi-tool will be essential. Using this tool, you can fix the power wire in the designated terminal of your ignition switch effectively.

11. Connecting Cables Accordingly

After you have carried out the steps detailed above, you will need to take hold of the accessory cable, ensuring caution at every stage. Then you can go ahead and link it to the designated terminal – which is the “ACC” terminal. This wire will be able to showcase its functions and prove to be of use whenever the vehicle is put in the “ACC” position.

Once you have connected the accessory wire, you must connect more cables. The second one you will need to work with is the starter wire, which must also be connected to its “ST” terminal. Finally, you can take the ignition wire and plug it into the ignition terminal labeled as “IGN” with proper caution and precision.

12. Reinstalling the Switch

After connecting the ignition wire, the starter wire, and the accessory wire, you will now need to move on to the next crucial action step of the process. Now that the ignition switch has been wired, you must reinstall it.
This will require you to place the switch back in its place, and you will need to repeat the previous procedure you carried out with the release pin. Once the wiring has been finished, press the pin gently and release it to return the switch.

13. Testing and Reassembling

Finally, you will need to test whether or not the newly wired switch is working as it should. This means you will need to test-run the ignition switch, and this can be achieved by first ensuring that all the battery terminals are connected once again. Doing this should usually make the ignition switch operate properly, but there is always a chance it may fail to do so.

In that case, you might need to reassemble the components once again and attempt to repeat the procedure you carried out previously, this time making sure to get even greater care when it comes to precision. You also need to ensure the car is completely shut down before you attempt to wire the ignition switch. As long as you follow the instructions really well, you should be able to spot the ignition switch wired and working very soon.
