Left side of the pic. It's cracked, connects by 2 wires (a blue and a white). Goes to a bundle and out of sight.  Thought I'd check here before making a 30 mile trip to the nearest dealer.

Ask….and ye shall receive.  There are all sorts of “thingies” that the car boys are putting on.  There is USUALLY a high current fuse on the positive.  I always carry a spare in every vehicle.

NOW….this device is basically….a sophisticated “Battery temp sensor” with a “amp meter” probe….and a “bonus”….Voltage sensor. Critcial to the voltage regulation of your alternator…..it goes bad….you COOK your battery….

You can google it and there is a LOT of info, some wrong…LOL, about it and what all it does….
