Subaru SVX 1991-1995 Haltech Nexus Wiring Harness (BF29238)

The SVX's EG33 flat-six has more to give than the factory ECU ever let it show.

The Subaru SVX is a smooth, capable grand tourer, but its factory engine management is decades old and closed to tuning. The Boomslang PNP Wiring Harness for the Haltech Nexus connects directly to your factory harness without any permanent modifications, giving the Haltech Nexus full standalone engine control. No cutting, no splicing, fully reversible.

Advantages

• Fuel and ignition maps built around your exact engine, intake and exhaust, not 1990s factory averages
• A clean foundation for engine swaps, forced induction or a fully built EG33
• Modern data logging and diagnostics on a platform the factory ECU never supported
• Throttle response and drivability you can tune instead of live with
• Confidence that what happened on the dyno is what happens on the road

Features

• Plug-and-play fitment for 1991-1995 Subaru SVX, manual or automatic transmission
• Compatible with Haltech Nexus R3, R5, and S3 ECUs
• No cutting or splicing of factory wiring
• OEM-quality connectors, USA-built by Boomslang Fabrication
• Fully reversible, factory harness preserved
• For competition and off-road use

The Details

Built specifically for this vehicle's connector layout with OEM-spec connectors and correct wire gauge throughout. Your factory harness stays completely untouched and the car can return to stock at any time. The Haltech Nexus takes full engine control once installed, giving your tuner a clean vehicle-specific foundation to build a proper map from.
