Replacing battery cables
 

Realized after a couple failed ignitions that my battery terminals have gone to hell. Was going to immediately swap out the positive battery terminal as it no longer properly sits on the post, $6 for replacement seems worth it rather than jerry rigging it. I do not see any wear on the cable itself and seeing as how its 130 to replace...i may hold off.

BUT my negative cable is junk. When shopping i noticed its 2 parts but I dont know which i need. Any help would be greatly appreciated...also it would seem this way but the negative upper cable already includes the terminal connection ($4 piece)...can anyone confirm that?

each part of the negative is 30 or so, I dont mind buying both but is that something easily attached (screwed on?) I tried searching but found nothing other than the battery relo diy

is the ebay posting attached both parts already connected for me?
