Product details

Known as the Heavy Duty OBDII Y-Type Diagnostic Wiring Harness, this multi-branch adapter is built to split a single OBDII port into two directions: one path leading to a standard OBDII female connector for parallel tool connection, and the other integrating Molex 20Pin and BMW 10Pin interfaces for multi-system truck diagnostics. It features an inline 3A fuse on the positive circuit, safeguarding sensitive diagnostic equipment from unexpected voltage spikes common in heavy-duty vehicles. The main cable uses UL2464 certified black PVC jacket, providing excellent resistance to abrasion, oil, and temperature fluctuations in busy repair environments.

As part of our flexible custom wiring harness solutions, this Y-shaped assembly can be adjusted in branch lengths and pin configurations to fit different truck diagnostic tool housings and connection layouts. Our engineering team carefully balances wire gauge and signal integrity to prevent data loss when multiple tools are connected simultaneously.

Drawing on our expertise in custom electrical wiring, we also offer full customization of pin assignments and connector types to align with specific truck ECU protocols and regional standards. Every crimped terminal undergoes rigorous pull force and continuity testing to eliminate loose connections or intermittent signal issues.
