2013 300xs ground cable location

[FastBird]

Trying to rig this motor (1E051884) on my old tub. Cant find where the ground cable goes. Mechanic who pulled engine started it went below starter. But I cant tell for sure where it goes.

Any pics would be great.

Thanks!

Starboard side of motor behind plenum very close to where the pressure line for the oil tank is connected, A lot of wires and oil lines in that area, just little to the left of where the 7 oil lines connect to the oil pump

Easier to get to if you disconnect the 14 pin keyswitch harness, and carefully remove the engine-side of the connector from it's bracket, so that you can pull the harness back a few inches and gain access to the bolt for the ground cable.
