Gauges
Identifi cation
Gauges come in two distinct variations: the i2000 series and the i2200 series. While similar in many
aspects, each series has it’s own unique compatibilities and connections.
The i2000 Series
Th i2000 series gauges come in both 2” and 3” sizes, depending on function. They are connected to the
CAN Bus through the i2001.
Only one i2000 series gauge needs to be plugged directly into the i2001. Once this is done, there is
a cable on the back of each gauge that connects to any other i2000 series gauge, which may be strung
together in any order.

The i2200 Series
The i2200 series gauges are similar in frontal appearance to the i2000 series but differ in most other
aspects. Unlike the i2000 series, the i2200 series gauges do not require the i2001 box. It simply requires
the Tach guage to be connected to the CAN Bus fi rst. Once the Tach gauge is connected to the CAN Bus,
a connection is made to the speedometer and all other 2” gauges may be connected together in any order
as long as one is connected to the Tach harness.
