Plenty of solder there to fix right up. Add some solder to the tab heat ut up press on and hold. Good as new for a year more or so.

Is there any difference in the two post (bolts where TBC is connected) in front of the fuse box under the hood? Besides the size and color.

Do you mind shining some light on it?

Edit

I have TBC connected to them wire from the left side is connected to the right post and wire from the right is connected to the left post, this the only way they would fit.

The left post goes to #66 on the fuse block which is a 30 amp fuse and is for a trailer brake controller. The wire for it is along the fender between it and the fuse box.

The right post goes to #71 on the fuse block which is a 40 amp j-case fuse which you have to install. This is for providing power through trailer connector to whatever is being towed. The wire for this is under the brake booster. Whatever is drawing from this circuit will continue to run off the battery when the engine is not running.
