Hah! I literally have to blue tape with description on the wires as somehow I manage to forget which one is coming from where. I think it is some kind of vertigo inversion problem. When I am standing up fishing them thru the fire wall I can readily identify from whence they come. Then I crawl inside flip over on my back look up under the dash and simply have no recollection of what’s what. And for you eagle eyed ones the wire nuts on the floor are simply there for safety on the ends of pulled wire for extra future applications. No wire nut connections under dash!
