Took mine apart today and the wires were not touching the exhaust, but perhaps 1/2" away. Once I started fiddling with the wires to see the best way to tie up, they were laying on the exhaust. Verified SN matched the recall. I just tied up with a few zip ties. Below are some pics. Pretty easy job, about 15 minutes. 4 screws for the metal exhaust and 6 screws for the plastic cover. No existing caulk sealant around pieces removed so none added when I put it back together.
