Power connector

The table shows the pin numbers in the connectors and their purpose. In the last column we provide the color of the wire responsible for a given signal.

Pin no. in plug	Power connector 9 PIN male	Colour of wire in the bundle
1	constant power supply 10-30V (the tripmeter does not have a switch. If you do not have a plane in your vehicle, you can use an additional switch.)	red
2	mass	brown
3	ignition switch (connect it together with the red one to a constant power supply, then the tripmeter will not go to sleep in the start screen and menu, or connect it to the ignition switch to maintain this function)	yellow

8	reverse driving signal (connect to the wire on which “+” appears when reverse gear is engaged or connect to a switch that will simulate reverse driving)	grey

Connection to repeater

To connect to the repeater, you need a cable with appropriate connectors. If you connect the tripmeter with a repeater and an external device at the same time, e.g. Garmin you need to use a signal splitter.

Accessory connector

The accessory connector is used to connect a repeater, Garmin device or speed warning light.

ALWAYS use accessories available in our store. We do not recommend any other use of this connector.
