iJDMTOY 3-Pin CF-13 CF13 EP34 Electronic Flasher Relay Instruction Manual

1. Introduction

This manual provides detailed instructions for the installation and use of the iJDMTOY 3-Pin CF-13 CF13 EP34 Electronic Flasher Relay. This electronic flasher relay is designed to resolve the rapid flashing (hyper flash) issue that often occurs when upgrading incandescent turn signal bulbs to LED bulbs in compatible vehicles. It provides a normal flash rate without the need for additional load resistors or wiring modifications.

2. Product Overview

3. Compatibility

This electronic flasher relay is compatible with various vehicles manufactured between 1971 and 2005. It is crucial to verify your vehicle's original flasher unit before purchase and installation. Please compare the pin configuration, shape, and size of your OEM flasher with the images and specifications provided in this manual.

Note: This flasher does not replace all flasher units. Ensure your vehicle uses a 3-pin CF-13 (EP34) type flasher.

4. Installation Instructions

Installation of the iJDMTOY CF-13 Electronic Flasher Relay is a direct replacement process. No cutting, splicing, or additional load resistors are required.

1. Locate the Original Flasher Relay: The flasher relay is typically found in the vehicle's fuse box, either under the dashboard or in the engine bay. Consult your vehicle's service manual for the exact location.
2. Verify Compatibility: Before proceeding, visually confirm that your original flasher unit matches the 3-pin CF-13 configuration shown in Figure 3. Pay attention to the number of pins, their spacing, and the overall shape.
3. Disconnect Power: For safety, disconnect the vehicle's battery before removing any electrical components.
4. Remove the Original Flasher: Carefully unplug the existing flasher relay from its socket. It may require gentle wiggling or the release of a retaining clip.
5. Install the iJDMTOY Flasher: Insert the iJDMTOY 3-Pin CF-13 Electronic Flasher Relay into the vacant socket. Ensure the pins align correctly and the relay is seated firmly.
6. Secure the Flasher (if necessary): In some vehicle models, the physical dimensions of the new flasher may differ slightly from the OEM unit, preventing it from clipping securely into place. If this occurs, it is recommended to secure the flasher to the wiring harness or a sturdy, fixed part of the vehicle using electrical tape or a command strip to prevent it from bouncing around during driving.
7. Reconnect Power and Test: Reconnect the vehicle's battery. Test the turn signals and hazard lights to ensure they flash at a normal rate.

5. Operation

Once installed, the iJDMTOY CF-13 Electronic Flasher Relay operates automatically. It electronically regulates the current flow to your LED turn signal bulbs, maintaining a standard flash rate. This eliminates the rapid flashing (hyper flash) that occurs when the vehicle's original thermal flasher detects the lower power draw of LED bulbs, interpreting it as a burnt-out bulb.

6. Maintenance

The iJDMTOY 3-Pin CF-13 Electronic Flasher Relay is a sealed electronic component and requires no routine maintenance. Ensure it remains securely connected and free from physical damage or excessive moisture.

7. Troubleshooting

• Hyper Flash Persists:
  • Double-check that the flasher relay is fully seated in its socket.
  • Verify that the correct flasher type (3-pin CF-13/EP34) was installed for your vehicle. Some vehicles may use different flasher types even if they appear similar.
  • Ensure all LED turn signal bulbs are functioning correctly.
• No Flashing or Constant On:
  • Confirm the flasher is installed with correct polarity (if applicable, though CF-13 is generally plug-and-play).
  • Check for any blown fuses in the vehicle's electrical system related to the turn signals.
  • Ensure the flasher pins are making good contact with the socket terminals.
• Physical Fitment Issues:
  • If the relay is slightly too large for the original housing, it may be possible to carefully remove the outer plastic casing and trim it, as some users have reported. However, this should only be done if you are comfortable with such modifications and understand it may affect the relay's protection. Always ensure the internal components are not damaged.
  • If the relay cannot be securely clipped, use electrical tape or a zip tie to hold it in place to prevent dislodging during vehicle operation.
• Delayed Clicking Sound:

  Some electronic flasher relays may exhibit a slight delay in the audible clicking sound compared to traditional thermal flashers. This is generally a characteristic of the electronic design and does not indicate a malfunction if the lights are flashing correctly.
