Elite 750 + Mazda Miata (MX-5) NA Plug'n'Play Adaptor Harness Kit (HT-150622)

Everything an NA Miata needs to run on a Haltech Elite 750, in one box, with no factory wires cut.

The Haltech Elite 750 + Mazda Miata (MX-5) NA Plug'n'Play Adaptor Harness Kit pairs the Elite 750 ECU with the vehicle-specific plug 'n' play adaptor harness. One side of the adaptor carries the factory ECU connectors, the other plugs into the Elite, so the Elite 750 drops in where the stock ECU sat and the factory loom is never touched. It suits NA 1.6L and 1.8L cars with the two-plug, two-row factory ECU and a manual transmission. USDM OBD-II cars (1996-1997) are not supported.

The Elite 750 is a compact, IP67-sealed single-connector ECU that brings much of the Elite 1500/2500 feature set, six fuel and six ignition channels, flex fuel and on-board logging, to a lower price. It is tuned in Haltech's NSP software, the same package used by the Nexus range.

Already own the ECU, or want a different Elite? The same application is also available as: Elite 1500 ECU kit (HT-150922).

What You'll Feel

• A turbo or ITB NA that idles, cold-starts and runs the A/C like a stock car
• Real MAP-based load sensing in place of the factory flap-door air flow meter
• Six sequential injector and ignition channels, enough for a straight six or a three rotor without doubling up outputs
• A stock harness you can return to at any time

Features

• Elite 750 ECU: 6 injector and 6 ignition outputs, suits 1 to 12 cylinder and 1 to 3 rotor engines
