The Quickest Path to a Standalone Digital Dash
Wiring a digital dash into a vehicle without a supported ECU used to be a complex task involving pin-outs, crimping, and hours of diagram tracing. The Semi Terminated Stand-Alone Harness for iC-7 Display Dash changes the game. This harness is engineered specifically for the “Standalone” user—the hot-rodder with a carbureted V8, the racer with a mechanical diesel pump, or the enthusiast retaining a stock ECU that doesn’t support CAN data. It provides a professional, plug-and-play interface to the back of the iC-7 dash, with the other end featuring clearly labeled flying leads ready to be connected to power, ground, and your sensors. It transforms the iC-7 from a CAN-slave device into a fully independent monitoring system.
Engineering Deep-Dive: Simplified Connectivity
The harness is constructed using automotive-grade, high-temperature wire with color-coded insulation for easy identification. The “Semi-Terminated” designation means that the complex, high-density 34-pin main connector that plugs into the iC-7 is already professionally crimped and assembled at the factory. This eliminates the most difficult part of the installation. The breakout wires include dedicated inputs for Sensor Data (such as Tachometer/RPM, Coolant Temp, Oil Pressure, Fuel Level) and Switched Inputs (Left/Right Turn Signals, High Beam, Parking Brake). By providing these dedicated circuits, the harness allows the iC-7 to replace a traditional analog gauge cluster completely, retaining all the street-legal functionality of turn signals and warning lights within the digital display.
Operational Benefits: Reliable Data Acquisition
Using this harness ensures that your sensor grounds and power feeds are correctly isolated, reducing the noise that often plagues DIY gauge installs. The harness includes a dedicated CAN bus pair, allowing you to add future expansion modules (like a Haltech Wideband Controller or Tire Pressure Monitoring System) even if you don’t have an ECU. It simplifies the integration of the iC-7 Sensor Pack (HT-010001), as the wires correspond directly to the sensors included in that kit. This cohesive ecosystem approach guarantees that the data you see on the screen—whether it’s 8,000 RPM or 210°F Coolant Temp—is accurate and trustworthy.
Fitment and Compatibility

Summary & Includes
The HT-060300 Harness is the backbone of any standalone iC-7 build. It takes the guesswork out of wiring, ensuring a clean, reliable, and functional installation in any vehicle.
Includes:
- 1 x Semi Terminated Harness for iC-7
- 2 x 3mm ID Ring Terminals (for small sensor grounds)
- 2 x 4mm ID Ring Terminals (for chassis ground)
- 10 x 100mm Cable Ties
Wiring Note: Always solder and heat-shrink your connections to the sensor pigtails. Do not use scotch-locks or twist-and-tape methods, as these will lead to signal degradation and intermittent gauge failure.
