I don't know too much about cars but I recently bought a 1969 mustang and I decided to rewire using American auto wire (AAW) and I finally finished and ready to start the car, when I put the key into the on position the car immediately tried starting without me turning the key, it also made this noise like if it was overworking itself so I took out the battery and now I am in a tight spot and was looking for help thanks in advance for any replies as I'm new to forums.
