6th Gen Accord (98-02) Carbon Fiber MultiGauge

What is it?

The Accord MultiGauge is a drop-in digital gauge cluster designed for select 6th Gen Accords (1998–2002) that use the center digital clock / hazard assembly shown in the compatibility photo. If your dash does not match that photo, this product will not fit. It replaces the factory center clock/hazard assembly in the dash and turns that space into a live engine monitor — without changing the classic Honda interior look.

On the 320×240 color display, you get a digital clock plus real-time PCM data: RPM, speed, throttle, coolant and intake temps, MAP, battery voltage, fuel trims, O2 voltage, ignition timing, and a check-engine indicator when codes are present. No extra buttons, no touchscreen, no modern-looking add-ons — it looks like it belongs in a late-90s Accord because it is the clock spot.

What does it do?

• Live engine monitoring of RPM, Vehicle Speed (VSS), Throttle Position (TPS), Coolant Temp (ECT), Intake Air Temp (IAT), MAP, Battery Voltage (V-BATT), Short/Long Term Fuel Trim (STFT/LTFT), O2 Sensor Voltage, Ignition Advance
• Check Engine indicator when the PCM reports active/stored codes
• Wireless diagnostics & setup (via built-in WiFi)
• Connect with phone or laptop — no app required, browser-based
• Read and clear Diagnostic Trouble Codes (DTCs)
• Sync the dashboard clock from your phone
• Switch Metric / Imperial units
• 12h / 24h clock format
• Performance Mode (for fun — not dyno/drag-strip grade)
• 6-flick gesture from a standstill: Times 0–60 mph (Imperial) or 0–100 km/h (Metric), plus ⅛-mile and ¼-mile Re-arm with 2 flicks; exit with ACC OFF Over-the-air firmware updates
• 8-flick gesture locks the unit for wireless firmware upload from a browser
• Smart power management
• Low-power rest mode when ACC is off — clock stays accurate with minimal draw
• Integrates with factory illumination for dimming (on/off with headlight switch)

How does it work?

• Install the MultiGauge in place of the OEM center clock assembly (hazard switch transfers from your original clock — see Package Contents).
• Connect the included wiring harness to the stock clock connector (Power, Ground, ACC, Illumination).
• Route the included OBD2/K-Line cable to the driver-side OBD2 port and connect to Pin 7 (K-Line).
• Power on with the key in ACC or ON — the gauge talks to the PCM over ISO 9141-2 / K-Line OBD-II at 10400 baud and streams live sensor data to the screen.
• Stealth UI — no extra controls Everything is controlled with the factory headlight switch. Quick ON/OFF “flicks” within a 3-second window trigger hidden modes:
• 2 Flicks: WiFi Quick-Start (status, clock sync, code scan)
• 4 Flicks: Setup & Config (full web settings + on-screen instructions)
• 6 Flicks: Performance Mode
• 8 Flicks: Update Mode (OTA firmware)

• For safety, flick gestures are disabled while the vehicle is moving.

• Status indicators (center of display):

• Cyan dot — WiFi active
• Green / Red dot — PCM connected / disconnected
• Check Engine icon — active or stored trouble codes

Why did you make it?

I love the 6th Gen platform, but finding a used clock that isn’t scratched or failing is getting nearly impossible. Instead of hunting for 20-year-old plastic, I built something better: a direct OEM replacement that keeps the factory aesthetic while opening a window into the car’s brain — live data, WiFi diagnostics, and code clearing without ruining the classic Honda interior.

What makes it special?

Automotive-Grade PAHT-CF Construction — Manufactured in High-Temp Carbon Fiber Reinforced Nylon (PAHT-CF). Engineered specifically to withstand extreme interior dashboard heat (up to 300°F / 150°C) without warping or fading in direct summer sunlight, while delivering a stealthy, OEM-style matte black finish.

Stealth UI — 2026 technology hidden in a 1998 aesthetic. No touchscreens, no bolt-on pods, no extra switches. You control the entire system with flicks of the factory light switch.

Purpose-built for this dash — Not a generic OBD gauge in a 3D-printed box. Designed around the exact clock opening, hazard switch location, and harness pinout for the 6th Gen Accord center stack.

Real PCM integration — Direct K-Line communication with the factory PCM, not a generic Bluetooth OBD dongle lagging behind your phone.

Compatibility

• Required — all must match:
• Dashboard layout: Intended ONLY for vehicles with this type of clock assembly
• Engine: Validated on 4-cylinder (I4) and V6 platforms.
• OBD2: Vehicle must have a factory OBD2 port (1998+ US-market Accords)..
• Hazard switch fitment: Enclosure slot is designed for 2001–2002 style hazard switches. 1998–2000 hazard switches are physically different and will fit the current enclosure, but a bit on the loose side. You must transfer your OEM hazard switch — we do not provide one.
• Not compatible with: pre-OBD2 vehicles.

Package Contents — What You Receive

• Each order includes:
• Accord MultiGauge assembly, fully assembled and tested
• 3D-printed enclosure made with High-Temp Carbon Fiber Nylon (PAHT-CF)
• 320×240 color display (pre-installed)
• ESP32 control board (pre-installed)
• Internal wiring / jumper harness for plug-and-play clock-connector hookup
• OBD2 / K-Line data cable — pre-wired for connection to OBD2 Pin 7
• Digital installation guide (PDF link)

What's not included

• Hazard switch — not provided. You must remove and transfer the OEM hazard switch from your original factory clock assembly into the MultiGauge slot. This is required for a complete install and preserves your factory hazard function.Installation tools — basic hand tools for dash removal (panel tools, screwdrivers, etc.) are not included.
• Smartphone / laptop — required only for WiFi setup, code scanning, and OTA updates.

Installation Overview

• Remove the factory center clock/hazard assembly from the dash.
• Transfer the OEM hazard switch into the MultiGauge assembly.
• Connect the MultiGauge harness to the stock clock connector.
• Route the K-Line cable through the dash to the OBD2 port (Pin 7).
• Press the assembly into the dash opening from the sides — not the screen. Fit is intentionally tight. Detailed step-by-step instructions are included with your order.

Notes for Buyers

• Fitment policy: No refunds or returns for incorrect vehicle fitment if your dashboard does not match the reference photo and compatibility requirements above.
