Hi. I'm trying to get my 09 Mustang GT going after it sat for 3-4 years. There were a million mouse nests but there were only a few chewed wires that I found. The main ones are under the back seat on the driver side going to the fuel pump. There are two main wires that have a decent amount of exposed copper but there is also an uninsulated wire that is not not copper, maybe tinned or aluminum, and I have no idea what it is or how to deal with it. It seems strange that there would just be an exposed wire like that and I cut back the tape/wrap and it isn't a case of a mouse just chewing off the plastic coating. None of the wires are broken so I put electrical tape on them, then used wire wrap and then put more electrical tape on top of that but I have no idea what to do with that exposed braided wire or what it is for so I just kind of taped and wrapped it as a bundle too so it cannot touch any metal anywhere. I know that I should fix all of those wires properly but I'm still testing things to make sure the car is even going to run and I need the fuel pump to work so I can get rid of the old gas in the tank. In input is appreciated. Thanks.
