You need two, because the purple wire activates the starter relay/solenoid, and the big one supplies the large current load to the starter. There is no ground, because the starter grounds through the engine block.

go ahead and ground that 3rd connection... you will see what 700 cca looks like first hand.... do not put any grounds onto that starter or those lugs... it will end badly for you!!!!

Re: 5.3 starter wiring
I know I should not have, but we all have to admit, I did snicker a bit. Looks like wasted income said it best. Best to ask questions than to make Xmas like sparks in mid summer.
