Elite 2500 + Toyota 2JZ IGN-1A Terminated Harness Kit Injector Connector: Bosch EV1

High-Energy Ignition Solution for the 2JZ

For high-boost 2JZ builds, the ignition system is often the limiting factor. The Elite 2500 + Toyota 2JZ IGN-1A Terminated Harness Kit is the ultimate engine management package for those upgrading to the massive spark energy of IGN-1A “smart” coils. This kit combines the flagship Elite 2500 ECU with a terminated engine harness that features a specific sub-harness designed to plug directly into IGN-1A coils. This eliminates the complex and critical wiring required to supply high current to these inductive coils, ensuring maximum performance without the risk of voltage drop or noise interference.

Engineering for Maximum Spark

IGN-1A coils are renowned for their output, but they are current-hungry and sensitive to grounding. This kit’s harness is engineered with the correct wire gauge and grounding architecture to support these coils safely. The main harness utilizes Bosch EV1 injector connectors for compatibility with modern high-flow injectors. The kit creates a plug-and-play environment where the user can simply mount the coils, plug them in, and start tuning, confident that the dwell times and discharge rates are fully supported by the hardware.
