Review on 🔌 ACDelco GM D2256C Park/Neutral Position & Back-Up Lamp Switch: Genuine Original Equipment for Reliable Performance by James Nedumaran

NSBU is relatively easy to install. The hardest part is removing the connectors, which are held in place with some sort of non-hardening substance to protect the metal connectors from moisture, which makes sense. If you apply a steady, slow but strong pull, it will slowly slip off. Do not use a screwdriver or similar tool to cut. The substance inside is very flexible and the impact action can damage the connectors as the connector bounces and then rebounds. Therefore, a strong, steady, and slow tug on the plug is enough, believe it or not. This action stretches the substance, preventing it from bending backwards and yielding. Advice only. The product offers some better water management features that the original didn't have. The non-critical error codes were cleared as soon as I replaced them.
