OneGauge OBDII Kit


This product is designed for OBDII enabled vehicles (those made in 1996 or later in the U.S.) and reduces the number of sensors you have to install. It can also communicate with CAN-BUS enabled engine computers available from many aftermarket manufacturers.



This product is designed for OBDII enabled vehicles (those made in 1996 or later in the U.S.) and reduces the number of sensors you have to install. Different vehicles and ECUs offer different sensor options, so please reach out if there are any critical sensors you want monitored. For vehicles without OBDII capabilities, you will need to purchase the OneGauge Hub, available here.

This kit includes:

  • OneGauge Hub with power wiring and basic ABS box
  • 7″ Touchscreen LCD
  • OBD-II connector (wired or wireless)

For details on all components, please see our OneGauge Instruction Manual. 

Please note that not all gauges are available in all vehicles; every engine, make, and model sends different sensors and information. Please contact us with any questions before purchase to ensure that you get access to all critical information for your dash.\
