Default Camry 2012..part # 82720-33250 engine block assembly box.

I was charging my battery on a 2012 se Camry and somehow burned out that relay junction box big buned spot inside also burned a small white and green wire connected to it. Fix the wires and disconnected the box. The car starts up fine no dash lights everything seems to be working. Can anyone clue me in onnthe purpose of this box. Its the box inside the fuse box next to the ecu. I also grounded those two wires together on same ground. Could that cause the box to burn? Im not sure if I cross connected the charge cables on the battery I panicked and disconnected them.realy quick. Remembered hearing the fan turn on while I was starting the car. Maybe its for the cooling fans???

Integration and relay box. These devices use solid state components to integrate and control the cars electrical circuits.

Check systems for function such as headlights, head light auto on/off, auto high beam, DRL, dome and dash lights, rear defogger, and the fan you noted..

Suggest finding a replacement by make, model, year and part number.

When installing said replacement make sure the unit is grounded properly per the bulletin below.
