HARNESS OVERVIEW If you are using a factory harness and are after an easy ECU upgrade this is a product for you! These adaptors plug directly into your Haltech ECU and have a set of factory connectors on the other side which plug straight into the factory harness. A simple Haltech Plug'n'Play product that allows you to be up and running in just a few hours. The quick start guide will walk you through installation of the Haltech Plug'n'Play adaptor into your vehicle.

Suits: Mazda Miata (MX-5) NA 1.6L and 1.8L with 2-plug, 2-row factory ECU. Manual transmission only.

Includes: Plug'n'Play adaptor harness, M14 x 1.5 air temp sensor with matching plug and pins, auxiliary I/O 16 pin Tyco plug and pins.

Notes: Does not support USDM OBDII 96-97, Special Edition SE and Anniversary models. All manual transmission 1.6L variants will require the factory throttle position sensor to be unplugged and removed. A full-range throttle position sensor alternative must be installed for correct functionality. Failure to do so will result in erratic behavior of the ECU at wide-open throttle along with damage to the ECU.

Features HARNESS FEATURES This harness when installed in conjunction with a Haltech Elite ECU opens the door to virtually limitless performance modification and tuning of your vehicle. Fully programmable systems allow you to extract all the performance from your engine by delivering precisely the required amount of fuel and ignition timing that your engine requires for maximum output under all operating conditions.
