Introducing the new LF701HT adapter harness which allows the XB LED headlights to be fully plug and play with high trim model trucks equipped with the OE LED projector headlights. This harness is completely plug and play and does not produce any error codes. However, these OE headlights have AFS (Adaptive Front Lighting System - shifts the lift left or right as you steer the truck). This is not a feature that will be maintained with the XB LED headlights - however, there will be no error codes because of this.
