Big 3 Upgrade

Currently working on installing the big 3 upgrade to my 98 ES300 but cant find the engine block ground, does anyone know where it is or has done the upgrade themselves?

It's on the transmission. Trace the wire from the negative terminal on the battery.

FYI: this kind of 'upgrade' is a bit pointless, but it also doesnt hurt.
