Elite 1500 + Mazda 13B S6-8 CAS with IGN-1A Ignition Terminated Harness Kit Injector Connector: Bosch EV1

High-Performance Ignition Solution for FD RX-7

The Elite 1500 + Mazda 13B S6-8 CAS with IGN-1A Ignition Terminated Harness Kit represents a complete modernization of the FD RX-7’s engine management and ignition system. This kit pairs the powerful Haltech Elite 1500 ECU with a purpose-built harness designed to support the massive spark energy of IGN-1A Smart Coils. Rotaries are notorious for blowing out spark under high boost; this system provides the infrastructure to run high-boost, high-RPM setups reliably.

Core Architecture & Technical Superiority

This kit includes a custom-terminated harness that bridges the OEM 13B S6-8 CAS directly to a bank of four IGN-1A smart coils (coils sold separately or as part of a larger bundle, please verify). The harness is constructed using high-temperature XLPE wire and features Bosch EV1 injector connectors, making it compatible with a wide range of high-flow aftermarket injectors. Crucially, the harness manages the high current draw of the IGN-1A coils, ensuring they receive stable voltage for maximum dwell performance without overheating the wiring.

Vehicle Fitment & Application Scope

Primary Vehicle Fitment:

• Mazda RX-7 (FD3S) Series 6, 7, 8 (13B-REW)
• Engine Swaps using the S6-8 13B-REW engine.

Ignition Note: Designed specifically for IGN-1A (Smart Coils). Will not work with factory coils.
