APSG NO SPLICE Ignition Coil Connector Plug Harness (2-Pack)

1. Product Overview

The APSG NO SPLICE Ignition Coil Connector Kit is designed as a direct replacement for damaged or worn original equipment manufacturer (OEM) ignition coil connectors. These connectors are crucial for maintaining proper engine performance by ensuring a secure and reliable electrical connection to your vehicle's ignition coils. Over time, original connectors can become brittle due to engine heat and environmental exposure, leading to poor connections, misfires, and reduced engine efficiency.

This kit provides a durable solution, eliminating the need for splicing wires, which can often introduce new connection problems. Each connector is engineered to meet or exceed OEM performance standards, offering resistance to high heat and moisture. It is suitable for both standard vehicle maintenance and modified vehicles with performance coil packs and ignition systems.

2. Safety Information

Always prioritize safety when working on your vehicle. Failure to follow safety precautions can result in serious injury or damage to the vehicle.

• Ensure the vehicle's engine is off and cool before beginning any work.
• Disconnect the negative terminal of the vehicle's battery to prevent accidental electrical shorts or activation of electrical components.
• Wear appropriate personal protective equipment, including safety glasses and gloves.
• Keep a fire extinguisher nearby.
• If you are unsure about any step, consult a qualified automotive technician.

3. Package Contents

Each APSG NO SPLICE Ignition Coil Connector 2-Pack includes the following components:

• Two (2) Connector Housings
• Eight (8) Metal Pins (four per connector)
• Eight (8) Rubber Seals (four per connector)

4. Setup and Installation

This section provides detailed instructions for replacing an existing ignition coil connector. It is recommended to replace one connector at a time to avoid confusion with wire placement.

1. Preparation:

   Before disconnecting any wires, take a clear photograph of your existing plug and wiring harness. Ensure the photo shows the plug with the snap release facing upwards, away from the engine. This photo will serve as a reference for the wire color coding and their positions during reassembly. Place a clean cloth or towel under the connector to catch any debris during disassembly.

2. Remove the Locking Insert:

   Locate the plastic locking insert within the old connector shell. Using a jeweler's screwdriver or a pick tool, carefully insert it into the slot on the underside of the connector and gently pull out the locking insert. This insert secures the wires in place.

3. Disassemble the Old Connector:

   With the locking insert removed, use a jeweler's screwdriver or pick to carefully break away the brittle black plastic that surrounds the metal wire ends inside the old connector shell. The aged plastic is typically fragile and should break away easily. Ensure all plastic pieces are removed to expose the metal terminals.
4. Remove Wires from Old Connector:

   Once the metal wire ends are exposed, gently pull the wires from the back of the old connector shell. They should slide out without significant force if all the old plastic has been successfully removed. Do not pull forcefully, as this may damage the wires or terminals.

5. Install Rubber Seals and Insert Wires into New Connector:

   Before inserting the metal pins into the new connector housing, slide a small red rubber seal onto each wire, ensuring it sits snugly against the metal pin. Refer to your reference photograph to insert the wires into the new connector shell in the correct order. Ensure the connector's release button faces upwards, matching the orientation of your original photo. Push each wire into the connector until you hear a distinct "click," indicating that the metal pin has locked into place.

6. Insert New Locking Ring:

   Once all wires are securely in place, insert the new white locking ring into the assembled connector. Ensure that the slot in the white ring faces downwards, towards the engine, to properly secure the pins.

7. Final Inspection and Connection:

   Before connecting the new harness to the ignition coil, carefully inspect the inside of the coil receptacle. Ensure there are no broken pieces from the old connector that could obstruct the new connector from seating properly. Once clear, firmly push the newly assembled connector onto the ignition coil until it clicks and locks into place. Reconnect the vehicle's battery negative terminal.

5. Operating

Once properly installed, the APSG NO SPLICE Ignition Coil Connector functions as a direct electrical interface between your vehicle's wiring harness and the ignition coil. Its purpose is to transmit the necessary electrical signals to the ignition coil, enabling it to generate the high voltage required for spark plug operation. A correctly installed connector ensures consistent power delivery, contributing to efficient combustion and overall engine performance.

The robust design of the connector, including its weather seals, helps protect the electrical connections from moisture, dirt, and engine bay contaminants, ensuring reliable operation under various conditions.

6. Maintenance

The APSG NO SPLICE Ignition Coil Connector is designed for durability and minimal maintenance. However, periodic inspection can help ensure its longevity and continued performance:

• Visual Inspection: During routine engine checks or spark plug replacements, visually inspect the connectors for any signs of physical damage, cracks, or discoloration.
• Connection Security: Gently check if the connector is firmly seated on the ignition coil. A loose connection can lead to intermittent issues.
• Cleanliness: If the connectors appear dirty, carefully clean them with a non-conductive electrical contact cleaner. Avoid using harsh chemicals or excessive water.
• Wire Integrity: Inspect the wires leading into the connector for any fraying, cuts, or exposed insulation.

7. Troubleshooting

If you experience issues after installing the new connectors, consider the following troubleshooting steps:

• Engine Misfires or Rough Idling:
  • Check Wire Order: Verify that the wires were inserted into the new connector in the correct sequence, matching your reference photo. Incorrect wiring is a common cause of misfires.
  • Secure Connection: Ensure the connector is fully seated and locked onto the ignition coil. A loose connection can cause intermittent misfires.
  • Pin Seating: Confirm that the metal pins are fully inserted and locked within the connector housing.
• Check Engine Light (CEL) with Misfire Codes (e.g., P030X, P035X):
  • Scan for Codes: Use an OBD-II scanner to retrieve diagnostic trouble codes. Misfire codes (P0301-P0308) or ignition coil primary/secondary circuit codes (P0351-P0358) indicate an issue with the ignition system.
  • Inspect for Damage: Re-inspect the connector and wires for any damage that might have occurred during installation.
  • Verify Coil Function: If the connector is confirmed to be correctly installed, the issue might lie with the ignition coil itself or the spark plug.
• Connector Not Seating:
  • Clear Obstructions: Ensure there are no remnants of the old connector or other debris inside the ignition coil's receptacle.
  • Correct Orientation: Confirm the connector is aligned correctly with the ignition coil's pins.

If troubleshooting steps do not resolve the issue, it is advisable to consult a professional automotive technician.
