Battery wires

I need to know where the wire that goes to the 40-amp green fuse that connects to the battery, where does the other end hook up. I am the second owner and don’t know why but a few wires are put back with just self-tappers and the wire to this fuse fell off and I cannot start my vehicle. I had no issues until it fell off. I just need somebody to either tell me or go and look at their compass and tell me.

If the yellow wire has power now, does the pink/orange wire have power to the relay? That power comes from the ignition switch and is what causes the relay to actuate and send power from the yellow wire.

It was late when I got it wired up and tried it and when it didn’t work, I just gave up. It was clicking at the BCM at my feet when I would hit the start button.

If you feel the BCM clicking, check to make sure the 7.5-amp fuse (fuse 51) is good at the BCM (fuse panel in vehicle).

Let me know.
