Jump Start a Maserati Granturismo S

[Smiler123]

My battery is flat on my Granturismo S and I cannot get into the boot to access the battery because the manual pull cable under the rear seat does not seem to work.

I have opened the hood and I am trying to find the positive and negative terminals to connect a battery pack to either jump start the car or simply to allow me to open the boot.

Does anyone know where they are in the engine bay?

Any assistance greatly appreciated.
