7 pin trailer plug

before i go tearing into this thing, i figured i should ask here first.
on my 02, the previous owner did some butchering at the 7 pin. there are 4 wires hanging alongside it with crimp connectors on the ends with cut wires in them. i figure he wired in a 4 pin instead of using an adapter.

the other night, i needed to use the car trailer, and have no brake lights/ directionals.
i do have running lights though.

are the superdutys like the chevy heavy dutys with individual fuse protection on the trailer plug circuits, or did this guy hack up the electrical system??

Yes, the trailer circuits are fused in the underhood fuse/relay box. Usually 2 10amp fuses for right and left turn/brake lights.

The pinout of the connector is in this towing forum. Either do a search, or just keep looking down the list. It's been posted here a number of times.
