Help with identifying wires for fuse box

I own a 2004 vw beetle 2.0 and don’t know the name of the wires circled above. I’ve looked at diagrams and all of them show the car having 5 wires hooked up to the fuse box but those were on 05 and up models. I believe it’s an alternator wire and a fuel pump wire. Unsure because on all diagram s the alternator wire is on the slot furthest to the right and this one is one left of that. The wires are melting and don’t know why.
