Elite 1000-2500 Mazda RX7 FD3S-S6 Plug ‘n’ Play Adaptor Harness

Seamless Rotary Integration: Elite Plug ‘n’ Play Adaptor for FD RX7 (Series 6)

Unlocking the full potential of the 13B-REW rotary engine requires precise engine management. The Haltech Elite Plug ‘n’ Play Adaptor Harness for the Mazda RX7 FD3S Series 6 (1992-1995) is the bridge between your factory wiring and the advanced capabilities of the Haltech Elite ECU range (1000, 1500, 2000, or 2500). This adaptor allows you to plug a Haltech Elite ECU directly into the factory wiring harness without cutting or soldering a single wire. It preserves the vehicle’s original wiring integrity while granting access to modern tuning features like volumetric efficiency fuel modeling, advanced boost control, and engine protection strategies.

Factory Functionality, Race-Ready Control

This adaptor is engineered to support the factory dashboard gauges, air conditioning, and power steering functionality, ensuring the car remains street-friendly. It is compatible with the factory twin-turbo sequential system or can be easily configured for single-turbo conversions. The kit includes an external M14 x 1.5 Air Temp Sensor for faster response than the stock unit, and an auxiliary I/O plug to add extra sensors (like Flex Fuel or Fuel Pressure) not present in the factory loom. Designed specifically for the Series 6 (2-row ECU plug) manual transmission models.
