Install the Ehubo2

NOTE

• The engine must be turned off prior to installing the Ehubo2.
• Do not connect in any way to a CANBUS or other engine management system.
• Power supply must not be taken from any ABS/EBS braking system.
The Ehubo2 needs a permanent power source and a good view of the sky to operate 
optimally. While the vehicle is off, the Ehubo2 will shut down to a low power mode and will 
draw a very small current from the vehicle supply. Remove the Ehubo2 permanent power 
fuse if the vehicle is in storage or parked up for more than a month to avoid discharging the 
vehicle battery.  
 
 

WIRING

The Ehubo2 is fitted with a wiring loom which is 
used to connect to the vehicle and for optional 
digital inputs.
