Working installation documented on a 1997 ATTS 5th-generation Prelude, retaining airbag, horn and cruise control; after refitting, the SRS light went out 8 seconds after start and horn, cruise, indicator self-cancel and ATTS all functioned. The wheel and inflator connect via the existing cable reel - no wires are cut. The author confirms the same concept works for: CTR or S2000 wheel onto EM Civic, EJ Civic and 5th-gen Prelude, and an EJ wheel onto a 5th-gen Prelude. It does NOT work on cars whose SRS ECU mounts to the inflator's back inside the wheel (4th-gen Prelude, EG Civic, EK Civic per the author) - those wheels are not interchangeable. The S2000 wheel uses the whole airbag pad as the horn; the CTR wheel has horn buttons either side. A JDM S2000 wheel is needed for cruise buttons - Australian-delivered S2000 wheels have none. If the SRS light latches on (e.g. from cranking with the inflator disconnected), reset the SRS ECU via the yellow 2-wire service connector under the dash near the fuse box: ignition on with the connector bridged, unbridge within 4 seconds of the light going out, rebridge within 4 seconds of it coming back on - the light then blinks twice to confirm reset (battery disconnection alone will not clear it).
Two modifications are required for an ATTS 5th-gen Prelude. 1) The ATTS Prelude wheel hub has an extra notch for an ATTS sensor that the S2000 wheel lacks: line up both wheels, mark the notch position, and grind a matching notch (same depth, same location) into the S2000 wheel hub with a die grinder, file or angle grinder (on the correct side). The notch does not stop the wheel being used later on a Civic or non-ATTS Prelude. 2) Cruise control re-pinning: the S2000 button pad uses a 5-pin connector while the Prelude uses 4-pin, so the pins are released (a 1N4004 diode works as a pin tool to spread the retaining tabs) and the Prelude cable-reel wires are inserted into the S2000 5-pin connector as follows - cable-reel SET/Decel (position 3) to S2000 pin 5, Accel/Resume (position 4) to S2000 pin 1, common (position 5) to S2000 pin 3; positions 1-2 are the airbag inflator and 6 is the horn. S2000 button connector pinout: 1 = SET/DECEL, 3 = common, 5 = Resume/Accel. Removal/refit uses two T30 torx inflator bolts and a 14 mm steering wheel centre bolt.

Important Caveats

  • • No crash testing was performed - the S2000 airbag is not designed for the Prelude cabin, and airbag volume/shape differ between models. Fitting a different model's SRS wheel is entirely at the owner's risk.
  • • Never cut or re-solder any SRS wiring, never tamper with wires in yellow conduit, and never probe the inflator with a multimeter.
  • • Always disconnect both battery terminals (negative first) and wait 3 minutes before unplugging any SRS component.
  • • Never store or leave the inflator (airbag) face down - always face up in a cool dry area.
  • • Not applicable to wheels/cars whose SRS ECU sits on the inflator's back (4th-gen Prelude, EG Civic, EK Civic per the author) - those wheels cannot be swapped.
  • • Use a T30 torx bit on the inflator bolts (a T27 works but risks damaging the bolts); leave the centre bolt on a few turns while breaking the wheel free of its splines so it cannot fly off, and never tug the cable reel or the wires attached to it.
