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.

That may not be a wire ,I think it is just a wrap inside of the plastic wrap . I can look at a 07 I have parted out here to be sure ,I think that wire is still there
Those are definitely wires. They are definitely corroded. They have definitely been chewed by varmints.
Here is what I would do:
Go to the parts store and pickup a Holley in-line fuel pump for gas.
Use it to pump the fuel out of the fuel tank. Then... purge it with clean fuel and plumb it into your fuel feed line. Run the car from a gas can until you get the tank dropped and everything put back to normal.
This will at least let you get the engine checked out, up and running, without having to dump a bunch of time and money into the fuel system before you even know if the engine is worth a crap.

Well ,my brother cut all the connectors off the car or I would have cut it back in the harness and sent it to you. The tin foil looking thing is a wrap inside the plastic cover wrap . Get some wires the same color and cut out the part the dirty rat chewed ,slip shrink tube over the wire first ,solder in the new piece , slip the sprink tube over the soldered connection and shrink the shrink tube then replace the plastic cover wrap.
The rabbits got my oil sender wires twice and got my brother's once ,they must taste good or somthing ,that is how I repaired them
