However, wiring a five-pole ignition switch will become very easy once you understand the code and figure out where to put the wires. Just open your vehicle’s hood, identify the wires, strip a part of the wire, sometimes ¼ inch, find the poles at the back of the ignition switch, and insert the ignition switch in the dash.
You will find the detailed explanation of each step you need to follow to wire a five-pole ignition switch below. Keep reading.
5 Pole Ignition Switch Wiring
People find it difficult to wire a 5 pole ignition switch because the labeling of the OEM and replacement switches is unclear. However, once you figure out the code’s information and understand where each should go, you will find it very easy to wire a 5 pole ignition switch. Continue reading to know the steps you should follow;
5 Pole Ignition Switch Wiring Diagram: Step 1
Park the vehicle and start by opening your hood, check the negative terminal of the battery, and detach the terminal locking nuts holding it to the negative post on the battery. Detach the negative cable from the post and take a 15-minute pause for the stored current in the vehicle’s electrical system to go down before you continue.
5 Pole Ignition Switch Wiring Diagram: Step 2
Locate all five wires you will connect to the ignition switch, and match each of the five wires to the fuse box or wiper switch, headlights, radio, etc. First, connect the starter wire to the inline fuse before connecting it to the engine compartment. The battery wire will find a connection with the fusebox. In some cases, the accessory wire will do the same.

Strip down ¼ of the insulation of each of the five wires, then match a terminal connector to their ends with pliers. Opt for a ring-style terminal if the poles you find at the back of the switch are posts; opt for a female spade terminal if you find a male spade at the back.
5 Pole Ignition Switch Wiring Diagram: Step 4
Check the poles at the back of the switch to understand the labels. Most 5 pole ignition switches usually have standard labeling; however, the location of each pole depends on the brand you got.
Wherever you find “IGN” or “87a” indicates where the wire to the ignition module or control should be. “BATT” or “30” symbolizes the battery wire, you will find “87” or “ST” at the center pole, and it indicates the starter wire.
Some poles indicate accessories you can use without starting the ignition or car engine. These poles are labeled “ACC,” “SU,” “X,” “85,” and “86,”. Once you are done, get a permanent marker and mark every point at the back of the switch so that you won’t have issues figuring them out next time.

5 Pole Ignition Switch Wiring Diagram: Step 6
Connecting the wires to the post at the back of the switch becomes easy when you start with the one at the top. Attach the headline wire to the post ” X” or “85” in joining the accessories wires. You might have a switch that doesn’t clearly show differences between the pole ” ACC” and pole “X” in situations like this; just make sure the headline wire is the only one attached to the pole. Then you can connect other accessory wires.
5 Pole Ignition Switch Wiring Diagram: Step 7
Most car users believe that the ignition switch is where they insert their keys and start the car. However, that’s the ignition cylinder. The ignition switch consists of the ignition cylinder where you insert your key to interface with the ignition switch; they function together.
It is an electrical component that decodes anti-theft in a key before turning on the electrical system and starting a vehicle. Once the electrical component is activated, the automatic transmission shifts out of the park.
The function of an ignition switch on a push-button start vehicle is to decode the anti-theft signal sent by the key fob, then activate the car engine. Suppose you insert your key inside the ignition lock, and nothing happens. In that case, the dashboard light doesn’t come ON as you turn the key to the ON position, indicating that your ignition is faulty and needs a repair or replacement urgently.
Nothing happening when you insert your key in the ignition switch could also mean something wrong with the wiring from the controller to the starter and the remaining electrical components. It could also indicate issues with the starter motor or your battery is dead.
Ignition Switch Wiring Color Code
The wiring color code could differ quite a lot, but generally;
- You should use the red color for the accessory connection
- The yellow color goes for the battery connection
- The green color is for the starter connection
- The blue color goes to the ignition system
