Some vehicles require a vehicle-specific piggyback adaptor to allow auxiliary lights to be installed using a standard wiring harness. This may be because the light bulbs are inside a sealed dust cap, or because the factory headlights use LED or HID technology.This piggyback adaptor allows the Hardkorr wiring harness to be used with the Isuzu RT D-Max and Isuzu RF MU-X with factory LED headlights (pre-August 2020 models). It will connect up directly to the 6-pin factory headlight plug, avoiding the need for cutting or soldering.The white T-connector on the back of the adaptor will plug straight into the connector on our wiring harness.
