Plug and Pins Only -Suit Factory Toyota 2JZ ign coil

Overview

Professional-grade connector and pin set designed specifically for Toyota 2JZ factory ignition coils. Essential for maintaining OEM reliability when retrofitting 2JZ coil-on-plug ignition to aftermarket ECUs or custom engine swaps. Eliminates the need to cut factory wiring looms while ensuring proper electrical connection integrity.

Technical Specifications

• Part Number: HT-030400
• Application: Toyota 2JZ factory ignition coils
• Type: Plug connector with pre-crimped pins
• Material: OEM-specification thermoplastic housing
• Pin Contact: Tin-plated copper terminals

Why You Need This

The 2JZ's factory coil-on-plug system is exceptionally robust, which is why many tuners retain the OEM coils even when fitting aftermarket ECUs. However, splicing directly into the factory loom creates reliability issues and makes future maintenance problematic. This connector set provides the proper interface between your Haltech ECU's ignition outputs and the 2JZ coils, maintaining the factory plug design that Toyota engineered for high-temperature durability.

Common applications include LS-swapped vehicles using 2JZ coils for their proven reliability, Supra builds transitioning from factory management to Haltech control, and custom engine swaps where builders prefer the 2JZ coil's compact packaging and performance characteristics. Without proper connectors, you're left cutting factory looms or bodging connections that will fail under heat cycling and vibration. These connectors ensure your ignition system maintains OEM-level reliability whilst gaining the precision control of standalone engine management.

ECU & System Compatibility

Compatible with the full Haltech Elite and Nexus range when configured for coil-on-plug ignition. The 2JZ coils work perfectly with Haltech's ignition outputs, providing excellent spark energy and timing accuracy.
