Product Overview LED Compatible Light Control Module ELM463 This unit is compatible with vehicles that have the trailer/towing package (see note below for vehicles WITHOUT trailer package). The electronic control module controls the combined front turn signals/daytime running lights, and the rear turn-signal/brake lights, as well as the hazard logic. Note: If your vehicle came with a blue version of this flasher (SF620), then that means your vehicle does NOT have the tow/trailer package. You can still use our ELM463 (= SF621) in this application, and install your own trailer/towing hookup wiring. A bracket (BR2) is available separately, but it may differ from the factory bracket, so save your old bracket if you can!
