2) With the engine’s ignition switch turned OFF, locate the Mercury 10-pin
CAN port on the engine / vessel. Depending upon the application two styles
of CAN ports may be available. Some engines / vessels are equipped with a
CAN junction box. You may connect the scan tool to any available port on
the junction box as shown in Figure 12.
Some applications have a free hanging 10-pin CAN connector located on the
engine’s electrical harness. To connect to this type of CAN port remove the
CAN connector’s protective cap (or terminator) and attach the scan tool.
