What Wires Go to Ignition Switch?

The ignition switch of the vehicle generally fails or even sparks during use. This is most likely caused by a wiring problem, and the circuit needs to be checked again. Because it is the most basic component that is used frequently, its replacement is inevitable. This article mainly introduces the wiring method and cost of the ignition switch, so that you can better understand the ignition switch.

What wires go to the ignition switch?

Battery firewire: This wire provides the main power supply to the ignition switch. It is directly connected to this terminal post through the fuse from the battery and provides power to the other three-terminal posts.

ACC: This wire is the output power of the electrical appliances used in the body, and equipment such as radios, interior lights, and cigarette lighters all rely on the power output from this wire to work.

On: This wire is the long-term live wire of the vehicle's electronic control system. The oil pump, instrumentation, and lights of the whole car all rely on the power output by this wire to work.

ST: This line is called the START line, which is the wire for the starter to operate. This is an instantaneous gear line. The ignition switch needs to be continuously turned to this position to output power to the starter, and it will automatically return to the ON position after it is released.

How to wire 3 wire ignition switch?

The three-wire power switch operates the electric smart device through three wires neutral wire, fire knife wire, and ground wire. It should be noted that the ground wire can only be connected to the top, where there are obvious signs, do not connect it wrong. The other neutral and live wires may be faulty, but also be careful not to let these two wires touch and not expose the wires to the outside of the switch.

The power switch can be divided into two types, one is a two-wire system and the other is a three-wire system. They are not very different, just an extra ground wire, and the ground wire has no voltage, just an extra power protection function. In addition, no matter whether the wiring is two or three, there must be a neutral wire and a live wire. The neutral line and live line are called L and N respectively, which are 220Vac. And the ground line is referred to as FG, which is directly grounded and has no voltage.

Cost of ignition switch

The ignition switch is a basic accessory of the vehicle, and the price is generally not very expensive. The ignition switch cost of construction machinery, including accessories and normal manual wiring installation costs, is less than 200 US dollars.

MYMRO offers the most competitive price for the ignition switch depending on the product specification and brand. The price ranges from 20 to 100 US dollars. Our engine parts are all OEM components and high quality.
