After installation of the 10,000 lb. winch, we went back to ensure all proper warning and instructional decals were applied in their proper places.
The instruction manual calls out 12469066 [ 7690-01-474-5928 / 7690014745928; Mile Marker 983-0021] being applied near the winch controller connector. Unfortunately, we did not receive that decal in our installation kit. Additionally, we were unable to locate an image of the decal, or even what it warned of.
Ultimately we were able to purchase the decal from Kascar, LLC who had several in stock. We purchased additional decals in the event we need them in the future, or were required to reproduce or make a similar decal for future installs. Below is a scan of that sticker for reference to the text included on it.
