TOYOTA issued a recall on the TACOMA and TUNDRA models

Equipment Description: Towing hitch kits and aftermarket trailer towing wire harness converters. Due to inadequate waterproofing performance and improper installation location of the converter, which is mounted on the exterior of the vehicle, an electrical short circuit could occur if water enters the converter housing. The short circuit can cause a failure of the converter, and if a trailer is being towed at the time, can also cause failure of the trailer lights. Correction: Dealers will replace the converter.
