cover what before engine foam

im looking to foam my engine but i want to make sure i cover only what is needed, and so far im not definite......

alternator, intake, ingition coils and spark plug wires, battery..

anything else? btw my pcm is just chillin below my intake naked to the elements, probably stupid not to cover it since its electric but should i? i'm quite lazy to cover anything i dont have to

I'd cover anything electrical, as the ingredients in engine shine products don't play well with electrical components.

cover anything electrical that isn't weather-protected, in the typical modern fuel-injected car you can just cover the alternator and start foaming assuming everything is buttoned tight the way it came from the factory. Unless you have a modified intake (WAI, CAI) you wouldn't need to cover it.
