It’s the EFI port. The yellow part is a snap in piece that melted. I’m trying to get more pictures from my son now.

This shouldn't be happening something is drawing to much current or a short
More than likely caused by poor contacts. The entire EFI circuit doesn't really draw that much current (roughly 6.25 amps protected with a 15 amp fuse), but poor contacts will cause arcing at the terminals or poor crimps will cause a high resistance. These are replaceable parts with pigtails that can be spliced in.

I thought about moving it , I haven’t seen that done anywhere though. If it made the problem go away, it would be worth it.

How did you secure it in the cab?
just zip tie it with all the relays behind the kick panel in the driver footwell.
