Water Damage Repair

I went to check on my trailer in storage this weekend and found some water damage in one corner. I found what I believe is the source of the water intrusion and I sealed it up with Dicor. I then ripped away as much of the paneling as required to expose the water damaged area and I tore out the insulation so that I could allow it to dry. It appears that a 2x2 stud in the very corner is totally rotted so I will need to replace that and there are a couple of other portions of studs that are pretty soft that will need to be repaired/sistered. Overall doesn't look too terrible. Since the trailer is almost 14 years old (Jay Flight 31BHS) I am going to see if I can repair it myself along with the assistance of a buddy who does a lot of construction. One thing that looks like it will take a bit of time is that a couple of the studs that will need replacing/repair have wires routed thru holes drilled in them. If I want to replicate that routing I will either need to cut and splice the wiring or try to find where they terminate so that I can pull them back and run them thru holes in the new studs. I'm thinking trying to rerun the wiring might be a little tricky so I wanted to see if anyone had experience dealing with this and what approach they would recommend.

Any and all input is appreciated.

Thanks.
