Elite 2500 + Mazda RX7 FD3S-S6 Plug 'n' Play Adaptor Harness Kit (HT-151328)

Everything a Series 6 FD RX-7 needs to run on a Haltech Elite 2500, in one box, with no factory wires cut.

The Haltech Elite 2500 + Mazda RX7 FD3S-S6 Plug 'n' Play Adaptor Harness Kit pairs the Elite 2500 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 2500 drops in where the stock ECU sat and the factory loom is never touched. It suits the FD3S Series 6 (1992-1995) with the two-row factory ECU plug and a manual transmission. Series 7 and 8 cars use a four-row plug and a different adaptor.

The Elite 2500 is Haltech's top-of-the-range Elite: eight injector and eight ignition outputs, drive-by-wire, control of up to four variable cams, dual-channel knock control and the full race function set. 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-150927).

What You'll Feel

• A 13B-REW that starts and idles on the Haltech base map the first time the key turns
• Boost that arrives the same way every pull, instead of the factory ECU's moods
