This kit is necessary if…you are installing a supplemental braking system with a monitor and the brake lights do not function when the vehicle is in the “tow” mode. …you are installing a supplemental braking system and the vehicle is equipped with a “retained accessory power” feature. (With this feature, the vehicle’s electronics continue to function normally for about ten minutes after the ignition is turned off. Then the electronics will no longer function, which shuts off power to the OEM brake light switch.)
