Mercury - CAN Data Harness (10-Pin, No Resistors) 1-Foot DTS Lead 84-879312T44. Overview. Digital Throttle & Shift systems rely on clean communication between modules, and sometimes the network needs a short, resistor-free link to tie everything together. The Mercury 84-879312T44 CAN Data Harness provides a compact one-foot connection that carries CAN 1, CAN 2, and CAN 3 signals without built-in termination. It's meant for DTS setups that already have proper network resistors in place and just n
