lINk CAN Bus CoNNeCtIoN
The Link CAN Gauge includes a CAN connection cable that is
pre-terminated to a DTM-4 connector. There is also a mating
DTM-4 connector kit included in the box. Use this connector kit to wire
into your vehicles CAN bus Pin out is shown below.

CoNfIGurAtIoN:
• The Link CAN Gauge includes a user-configurable 120 ohm
terminating resistor jumper. The resistor is enabled when the jumper is
in place.
Rear of Gauge
Terminator
• CAN networks require a 120 ohm resistor on the ends of the network
– one at the ECU, and one on the last device in the network (see
image below for an example). Leave the terminating resistor jumper in
place if the CAN Gauge is the last device in the chain of CAN devices.
Remove the jumper if there are already two terminating resistors at the
ends of the network (see below for an example).
• All Link G4+/G4X ECU’s have a 120 ohm terminating resistor fitted
• Having too many or not enough resistors can cause the gauge or other
devices to malfunction.
