I know there is one on the bottom of the engine block, right above the oil pan. I cannot remember which side it's on though.
there is also one on the exhaust towards the rear of the car. but I'm not sure about this one. I work on several cars and sometimes confuse these things between them.
but i know for sure that there is on next to the oil pan.
hope this helps.
Yes.
Intake side, in front of motor mount. Negative battery cable. Will be behind AC comp if its still installed.
Rear ox head on exhaust side (small ground) On bracket that holds the throttle controls, IIRC.
Ground on the trans Xmember (small ground) Drivers side, just a look going up to the actual trans, run through any of the Xmember bolts.
Ground On Trans bolt on intake side of engine, near starter... 2nd bolt up on intake side. Going near the fuel line junction... ish.
No pics, sorry. HTH
*edit*
Few of them on the block...
Two bundles under the intake, just bolt to the intake plenum.
One from the Coil pack

Super easy way
Google TSRM, click first link on the home page in the upper right hand corner is a tab TEWD click and search thru the menu it will have every single location of every single ground throughout the whole car . It is easy.
