I killed my 64 Dart GT Convertible.

And maybe soe one else will no why is there two wires going down to the starter my thanking is that its hook in with the hot side off the battery to give juice to the inside of the car and hot to the starter relay correct me I'm wrong so if its not the taped up wire the it has to be in the bulk head plug or the stearing wheel connection if not there then the ignition switch it self but my thanking could be wrong was just trying to give some ideals I still don't under Stand why the wire is missing from the starter relay switch unless its grounded out some how because from wiring diagram the wire from the neutral safety switch should hook there
