The STEDI Dual Connector DT-4 Plug & Play SMART Harness is engineered for high-current applications with robust single relay operation. Built with heavy-duty 10AWG cable and designed for both positive and negative switching systems, this harness makes installation simple without cutting or soldering, allowing up to 2 lights to run simultaneously with built-in Daytime Running Light (DRL) functionality.

Featuring 1 x 80A relay and a total harness capacity of 40A, it’s ideal for medium to high-powered lighting setups.

The harness automatically detects switch polarity and works out of the box on a variety of vehicles, including challenging models like Toyota, Ford Ranger and Mazda BT-50, and is protected by a 50A fuse.
