2\. Route along the implement, allowing slack at pivot points and avoiding snag hazards.

3\. Connect the **T3H-S001** adapter to the Front Extension Harness.

6\. Connect the **T3H-G002** adapter to the appropriate GNSS receiver port.

7\. If using NMEA 0183 Serial, also connect the NMEA extension harness to the **T3H-G002**, then connect the other end to the **T3H-C002** ECU breakout harness.
