📍 Step 1: Choose the Button Location

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

🔧 Step 2: Prepare the Wiring

Disconnect the battery to prevent shorts.
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.

🔌 Step 3: Wire the Button

Connect power and ground:
- 12V Constant (White) → Button Pin 2 (via in-line fuse).
- Ground → Bolt on the chassis (scratch paint for conductivity).
Relay Setup:
- Pin 30 → Starter Wire (Black/White).
- Pin 85 → Ground.
- Pin 86 → Button Pin 1.
- Pin 87 → Ignition Wire (Black/Yellow).

🔩 Step 4: Mount the Button

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

🚨 Step 5: Test & Troubleshoot

Reconnect the battery.
Turn the key to “ON” (do not start).
Press the button—engine should crank.
- No crank? Check:
  - Relay connections.
  - Fuse integrity.
  - Ground points.

🌟 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.
