Product details
Vehicle-specific T-harness
The Directed THHYN4 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 Hyundai/Kia smart key vehicles, years 2015-2020. DS4/DS4+ family; verify year/trim in Directechs. 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.
