๐Ÿ“ Step 1: Choose the Button Location

  • Flat, accessible surfaces: Dashboard, center console, or OEM key slot.
  • Avoid airbags: Check your vehicleโ€™s manual for safe zones.
  • Pro Tip: Use a template to mark the hole size (S2000 button: ~1.5″ diameter).

๐Ÿ”ง Step 2: Prepare the Wiring

  1. Disconnect the battery to prevent shorts.
  2. Remove steering column shroud to access ignition wires (Honda example):
    • 12V Constant (White): Powers the button.
    • Ignition (Black/Yellow): Activates the ignition circuit.
    • Starter (Black/White): Engages the starter motor.

๐Ÿ”Œ Step 3: Wire the Button

  1. Connect power and ground:
    • 12V Constant (White) โ†’ Button Pin 2 (via in-line fuse).
    • Ground โ†’ Bolt on the chassis (scratch paint for conductivity).
  2. Relay Setup:
    • Pin 30 โ†’ Starter Wire (Black/White).
    • Pin 85 โ†’ Ground.
    • Pin 86 โ†’ Button Pin 1.

๐Ÿ”ฉ Step 4: Mount the Button

  1. Drill and Dremel: Cut a hole for the button, ensuring a snug fit.
  2. Secure with epoxy or brackets for vibration resistance.
  3. Pro Tip: Use rubber grommets to prevent wire chafing.

๐Ÿšจ Step 5: Test & Troubleshoot

  1. Reconnect the battery.
  2. Turn the key to “ON” (do not start).
  3. Press the buttonโ€”engine should crank.
    • No crank? Check:
      • Relay connections.
      • Fuse integrity.
      • Ground points.

๐ŸŒŸ Pro Tips for Success

  • Immobilizer Bypass: For 2001+ Hondas, use an immobilizer emulator (e.g., AP2MOD).
  • LED Backlighting: Tap into the dash lighting circuit for nighttime visibility.
  • Waterproofing: Seal the button with silicone if exposed to moisture.
