Installation

Mounting Orientation

The default and recommended mounting orientation is flat with indicators facing forward for visibility.

  • Mount as flat as possible for best performance from the built-in accelerometer / gyro.

Alternative Mounting

You can mount the system in other orientations. For best accelerometer and gyro performance, it's recommended you mount in an orientation that's square to the orientation of the car.

  • Example:
    • Upside down
    • Vertical / on edge

If an alternate mounting orientation is chosen, you should re-map the accelerometer and gyro channels to reflect this change.

Connections

Plug Connector Type

The connector is a standard 24 pin Molex Mini Fit Jr.

  • Plug Housing: Molex Mini Fit Jr. 39012240
  • Compatible Pins: Molex 46018-1541 or 46018-1541
  • ProTip: a 24 pin Molex harness from a computer power supply can also work as a secondary wiring harness

GPS

Connect the included GPS antenna to this port.

  • Note: Tighten this connection to 5-6 inch/lbs (just beyond finger tight). Do not over torque

Cellular Telemetry

If optioned with the 3.5G real-time cellular telemetry module, connect the cellular antenna to this port.

  • Note: Tighten this connection to 5-6 inch/lbs (just beyond finger tight). Do not over torque

Antenna Placement Guide

GPS

For optimal GPS reception, install GPS antenna with a clear 360 degree view of the sky, such as on the roof of the vehicle.

Cellular antenna

For optimal cellular performance, install the cellular antenna on the roof of the vehicle, using the roof as a ground plane.

Antenna separation

It's recommended you separate the GPS and cellular antennas as reasonably far apart as possible, such as mounting at opposite ends of the roof. RaceCapture Pro MK3 antenna install.png

  • Note: - about 3 foot / 1 meter separation is ideal.

RJ45 CAN + Power connection

The RJ45 port provides connections for power and both CAN channels.

OBDII CAN cable

The RJ45 port is normally provided for the OBDII CAN cable accessory for a convenient plug and play OBDII connection

Custom Cable

You can also use a common RJ45 ethernet cable to provide power, ground and CAN bus data for a custom application.
