SensorX board
SensorX is a breakout board that provides multiple ground and 5v reference signals for up to 7 sensors, including spots for pull-up resistors for passive, two wire temperature sensors. It's specifically designed to be bundled in-line with your wiring harness and covered in heat-shrink tubing when fully assembled.
Wiring sensors
General wiring info
- Wiring Gauge: We recommend 22-24 gauge hookup wire to connect SensorX to your sensors.
- Splicing wires: Splice wires using a telegraph twist and use heat shrink.
- Get a friend This is a DIY project! If you're over your head, find a friend comfortable with wiring, soldering and electronics to help you out.
Sensors are connected to the right side of the SensorX board in groups of 7 sensor connections.
Passive / Thermistor Temperature Sensors
Most passive thermistor-based temperature sensors require a pull-up resistor to provide the variable voltage needed for the analog input for RaceCapture. The SensorX board provides locations to install pull-up resistors to ease the installation of these types of sensors.
To install the pull-up resistor, place one of the included 2.2K resistors in the diagonally placed location next to each RaceCapture input (1 - 7). Solder the resistor in place and clip the leads on the back, ensuring they are flush.
Once the pullup resistor is in place, you can wire up the two leads of the temperature sensor to the Ground (GND) and Input (IN_X) connections of the SensorX board.
- Ensure a good solder joint and clip the leads flush.
- You do not need to wire up the 5v connection since the built-in pull up resistor provides the voltage that completes the voltage divider circuit.
Active Sensors
Active type sensors require 3 connections:
- Ground
- 5v
- Output signal
Wire up the 3 connections to the sensor by connecting Ground (GND_X), 5v (5V_X) and Input (IN_X).
- Ensure a good solder joint and clip the leads flush.
Connecting to RaceCapture inputs
Once the sensors are connected to the Sensor Side of the SensorX board, you can route individual wires to the Ground, 5v reference and analog inputs of RaceCapture.

Final installation
When testing is complete, you can slip the SensorX board inside heat shrink tubing and bundle it in-line with the rest of your wiring harness for a clean installation. File:Sensorx heat shrink.jpg
