i did some research on the electronics of my sidecar, a URAL Ranger ( or Gear Up in the US) model year 2014. This machine uses an electronic fuel injection (EFI) instead of a standard carburetor. Unfortunately this means some additional reverse engineering to get full access to all aspects this machine.
1.) Which connector is being used?
The “protection” cap is also a working connector, but i didn’t want to use it, so i ordered another one from RS-components. (RS order number 511-0168)
Molex MX150L – 6 Pole / MOLEX 19418-0011

In addition to the connector, it is mandatory to insert the pins. (RS order number 511-0067)

2.) How to connect to a remote OBD device?
I used a OBD (on board diagnostics) cable extension 1m from ebay, which i cut in half and soldered the pins according to the schematic below
Molex connecter – OBD Pins
1 CAN HI – 6 CAN HI
2 CAN LO – 14 CAN LO
3 BAT GND – 4 chase GNDand 5 signal GND
4 BAT + – 16 Supply Voltage
resulting in the following cable
3.) Readout data from the motorcycle
For reading out the data i am using a DIAMEX Scandevil. This is a handheld ODB scanner, so no additional software is needet to read out data from the motorcycle. It is also possible to insert a SD card and store sensor values directly on the flash drive, while riding the bike.
My first tests worked out great, i was able to detect both EFI units, read out the sensor values like RPM, outside temperature and ignition timing.
