Ok, thanks. Not sure why anyone would cut that one. Not sure that one will live with a splice, probably look at replacing with a new piece.
It would seem someone cut it to disable the vehicle?
You could solder that connection there and be good. If your good you could solder it butting the ends of the wires. Other wise you overlap a small 1/2" long bare 10 ga wire to overlap the original cut wires. Shrink sleeve when done with double layers of shrink sleeve.
My red wire where it passed through the fuse block has been soldered together for 30 years. I have been driving the car a lot with AC and plenty of electrical load and no heat there anymore. Actually better than a plug.
