Is there a list anywhere that shows where all the important ground connectors are located at for all the different models of Chevy / GMC pickups?

So far on my truck I have found 3 ground connections... one coming from the negative battery cable to the passenger side cylinder head, another coming from the body to the driver's side cylinder head, and another under the driver's side floor board coming out of a wiring harness and connects to the frame.

I heard the ECM has it's own ground wire too towards the front of the truck but so far on mine I have not spent time looking for that one yet. (My truck is a 2011 Silverado 5.3L Ext Cab, 2WD)

Just curious is anybody know of a handy list that tells people where to find the ground connectors so they can be cleaned and maintained since ground connections are very important.
