Are you looking to add a little bit of flash to your vehicle? A 3 terminal flasher can be what you need. In this article, we will walk you through the wiring diagram of a 3 terminal flasher, and answer some frequently asked questions.
What is a 3 Terminal Flasher?
A 3 terminal flasher is a type of electronic switch that controls the blinking rate of your vehicle’s turn signals. It has three terminals: the X terminal, the P terminal, and the L terminal. These terminals are connected to the vehicle’s wiring system and are used to control the flashing of the turn signal bulbs.
The X terminal is connected to the power source, the P terminal is connected to the turn signal switch, and the L terminal is connected to the turn signal bulbs. When the turn signal switch is engaged, the 3 terminal flasher begins to cycle on and off, causing the turn signal bulbs to flash.
How to Wire a 3 Terminal Flasher?
Wiring a 3 terminal flasher is a simple process that involves connecting the X, P, and L terminals to the appropriate wires in your vehicle’s wiring system. Here is a step-by-step guide on how to wire a 3 terminal flasher:
Step 1: Disconnect the Battery
Before doing any electrical work on your vehicle, it is crucial to disconnect the battery to prevent electrical shock or short circuits.
Step 2: Locate the Turn Signal Switch and Bulbs
Locate the turn signal switch and bulbs in your vehicle. They are usually located on the steering column and at the front and rear of the vehicle, respectively.
Step 3: Identify the X, P, and L Terminals on the Flasher
Identify the X, P, and L terminals on the 3 terminal flasher. They are usually labeled on the flasher or in the packaging.
Step 4: Connect the X Terminal
Connect the X terminal to the power source. The power source can be the battery or a fuse box that is connected to the battery.
Step 5: Connect the P Terminal
Connect the P terminal to the turn signal switch. The turn signal switch is usually located on the steering column and is connected to the turn signal lever.
Step 6: Connect the L Terminal
Connect the L terminal to the turn signal bulbs. The turn signal bulbs are usually located at the front and rear of the vehicle.
Step 7: Reconnect the Battery
Once you have connected all the terminals, reconnect the battery and test the turn signals to ensure they are flashing correctly.
