Mercury - 2-Pin "Y" Adapter Harness CAN Link Splitter 84-896370T01. Overview. Some DTS rigs need a little more flexibility in how the CAN line runs, especially when the harness has to reach across a wide console or deeper rigging chase. The Mercury 84-896370T01 2-Pin "Y" Adapter Harness gives DTS setups a clean way to branch or extend the CAN network without cutting into the main harness. It keeps everything tidy, helps with longer runs, and makes the system easier to lay out when space is tight
