Models Affected: All 8’ ChallengerST Service Bodies mounted on 2024 GM Trucks
In order to continue providing exceptional support to our valued distribution partners, we want to share a recent communication from General Motors that will have a significant impact on your installation process. Below you will find GM Bulletin (194).
It has come to our attention that the 2024 GM trucks now feature multiple taillight configurations, depending on the trim level of the truck. While some of these light configurations have a separate wire for stop lights, the majority of models have combined wires for stop and turn signals. As a result, this GM change necessitates a modification in our approach to adaptor plugs on GM trucks. The esteemed STAHL Engineering team has devised the following approach:
- For every GM box removal truck, it is imperative to utilize adaptor plug 244046.
- For GM lighting arrangements that have a separate circuit for stop lights, an additional adaptor plug with part number 245091 will be required. There are two ways to determine which trucks will necessitate the second adaptor:
-
- Review the attached GM bulletin, which outlines both the trim levels with the extra circuit and how to identify them based on the taillight housings.
- During the testing of lights after body installation, if the stop lights are not functioning, please install the add-on adaptor.
Please note that these two steps pertain only to box removal applications. Factory box deletes and cab chassis’ will require a different adaptor approach.
We anticipate that the add-on adaptor will only be necessary for higher trim levels. We estimate that it will be required for approximately 15% to 20% of GM applications with an installed STAHL service body. For more detailed information, please refer to the attached communication from General Motors.
