1. Introduction
The Dakota Digital Cable Drive Sensor SEN-1011 is designed to convert a mechanical speedometer cable signal into an electronic pulse signal. This allows for the use of electronic speedometers, cruise control systems, or other electronic devices that require a vehicle speed input, while retaining the original mechanical speedometer cable. It is engineered for reliability and accuracy in various automotive applications.

2. Safety Information
- Always disconnect the vehicle's battery before performing any electrical work to prevent short circuits and electrical shock.
- Ensure all wiring connections are secure and properly insulated to prevent damage from vibration, heat, or moisture.
- Route cables away from moving parts, sharp edges, and high-heat sources to prevent abrasion or melting.
- Consult a qualified automotive technician if you are unsure about any installation steps.
- Do not modify the sensor or its wiring, as this may void the warranty and cause malfunction.

4. Installation
4.1. Mounting the Sensor
The SEN-1011 sensor is designed to be installed in-line with your existing mechanical speedometer cable. It typically connects to the transmission or transfer case output where the original speedometer cable attaches, and then the original cable connects to the sensor's output.
- Locate the speedometer cable connection point on your vehicle's transmission or transfer case.
- Disconnect the original speedometer cable from the transmission/transfer case.
- Thread the SEN-1011 sensor onto the transmission/transfer case output. Ensure it is securely tightened.
- Connect the original speedometer cable to the output side of the SEN-1011 sensor. Ensure this connection is also secure.
- Secure the sensor and cable assembly to prevent excessive movement or strain using appropriate mounting hardware or cable ties.

4.2. Wiring Connections
The SEN-1011 sensor requires three basic electrical connections:
- Red Wire: Connect to a switched +12V power source. This source should be active when the ignition is on.
- Black Wire: Connect to a good chassis ground. Ensure a clean, secure connection.
- White Wire: This is the signal output wire. Connect this to the speed input of your electronic speedometer, cruise control module, or other device.
Ensure all connections are soldered or crimped with high-quality connectors and insulated with heat shrink tubing or electrical tape to protect against environmental elements.

5. Setup and Calibration
The SEN-1011 sensor provides a raw pulse signal. The calibration process will typically be performed by the electronic device (e.g., speedometer, cruise control unit) that receives the sensor's output. Refer to the instruction manual of your electronic device for specific calibration procedures.
Common calibration methods involve driving a known distance (e.g., 2 miles) and allowing the electronic device to learn the pulse count per mile, or entering a specific pulse-per-mile (PPM) value if known.
6. Operation
Once properly installed and calibrated, the SEN-1011 sensor operates automatically. As the mechanical speedometer cable rotates, the sensor generates an electronic pulse signal proportional to the vehicle's speed. This signal is then transmitted to the connected electronic device, providing accurate speed data.
7. Maintenance
The Dakota Digital Cable Drive Sensor SEN-1011 is a sealed unit and requires minimal maintenance. Periodically inspect the wiring and connections for any signs of wear, corrosion, or damage. Ensure the sensor's mechanical connections to the transmission/transfer case and speedometer cable remain secure.
