WHY DO CATS LIKE EATING EARWAX ??

I did a study on earwax as part of my degree in neuroscience (Bsc.Neurosci. Nottingham 1997) , and know a fair bit about Sensory Reception in both humans and cats. . .

The principal constituent components of earwax are complex sebaceous fluids and sloughed off dead skin cells. The sebaceous fluids are composed mostly of triglyceride fatty acids, waxes and cholesterol esters.

I think you may have discovered something quite important here, the earwax is coincidental to cats liking to eat scabs, and I think that is the more interesting information. You may have proof, or are on the road to proof, of a symbiotic relationship between humans and cats -- and probably also dogs.

Cats like to lick earwax and scabs what about large oozing wounds ???

They would like that too wouldn't they, well then, is there something in their saliva that is a disinfectant, reduces infection in human's wounds ?

I bet there is and that is the symbiotic relationship, soldiers in the old days that had lots of pets that loved them would live longer because the pets licked their wounds when they fell in battle and allowed them to survive by increasing their chances of surviving infection.
