LSX240

ok so the yellow ended plug on the left was plugged in but when i went to trace it back the plug that it was connected to was not connected. it was just pigtails like in the pics below it.

this is the plug i found pigtailed



also this plug right next to the fuse box on the intake side of the car is not connected to anything. theres is a longer plug that is connected to something, the shorter one is whats not connected to anything


anybody know what these go to ?

p.s. my alternator is not providing power for the car, its not bad either, i tested it today and it passed. so yeah i unplugged my batter and the car shut off.
