Directed THHON9 Honda Acura T-Harness

Vehicle-specific T-harness

The Directed THHON9 is a vehicle-specific integration T-harness intended to speed remote-start and security installs by mating OEM-style connectors to compatible Directed control modules. It is designed to reduce cutting and splicing versus a fully hardwired install when the vehicle and harness revision match.

Fitment and system compatibility

Select Honda/Acura vehicles — Directed press cited Fit/HR-V/TLX; confirm in Directechs. DS4/DS4+; press noted as replacing THHON1; Directechs may mark revisions discontinued — verify. Always confirm the exact vehicle, ignition type, and harness revision in the Directechs vehicle configuration guide before ordering or installing. Coverage lists change as Directed revises harnesses.

Install notes

This harness is not a remote-start system by itself. Pair it with a compatible Directed module (and any required firmware flash). Professional installation is recommended.
