T3 OBDII Universal Harness Reference Guide

Special instructions about the new OBDII Universal Harness.

The updated OBDII Universal Harness (1005743) is designed to work across more vehicle types, which is why it no longer includes the traditional L-Bracket from older harnesses. Most vehicles will use Connector #1, which replaces the previous standard L-Bracket. Connector #2 is used for certain Ford vehicles that require a larger bracket style.

See the reference guide for more information.
