Auxiliary Battery
The auxiliary battery provision can be used to supply electrical power to additional equipment that may be added, such as a slide-in camper.
If the vehicle has this provision, this relay will be located on the driver side of the vehicle, next to the underhood electrical center.
Be sure to follow the proper installation instructions included with any electrical equipment that is installed.
Notice: Leaving electrical equipment on for extended periods will drain the battery.
Always turn off electrical equipment when not in use and do not use equipment that exceeds the maximum amperage rating for the auxiliary battery provision.
