@superdude5007 Who “he”? And buy what? I’m not certain what you’re asking about.
In terms of the tutorial I made here with Brian… we do go off of a general schematic which labels what solder points affect what actions (i.e. on-off switch, aux switch, batteries, LED, etc. etc.).
Otherwise, if you feel confident with soldering, wiring, layout and planning… you can just refer to the .PDF that Erv has on his website.
