• Off-road, competition, and other modified applications where applicable

Kit Features:
• Factory-style mating connectors
• Helps seal and protect unused electrical connections
• Helps prevent moisture, dirt, and debris intrusion
• Clean, professional installation
• No cutting or modification of the factory wiring harness required

Important:
This is the base tuner harness plug kit. It does not include plugs or caps for the EGR system, DEF tank components, or SOFT tuning applications. Those components are available separately where applicable.

Please verify the connectors shown in the product photos match the connectors on your vehicle before ordering.
