This harness is intended to allow the use of 2024-2026 FULL LED tail lights found on the 2500 3500 trucks to be used on a 2019–2026 CHEVROLET/GMC 1500– 3500 halogen or 6pin LED truck. The animated sequence at unlock is not functional as this is a function of the BCM of the 2024 -26 truck, instead of the animated sequence.
