I ended up selling my pull behind RV and no longer had a great need for my 2021 GMC 3500. I removed the SB Filters MAP Sensor Relocator before selling. This relocator block is used but is like new and in use for less than 15,000 miles. I also am including a new MAP sensor GM #12681993 I had carried as a spare. These are available for pickup in Central Colorado. Price includes shipping anywhere in the Continental US. These items should fit any L5P vehicles.
