Hi and welcome from SoCal San Diego.
Sounds like you have a number of issues.
First- before random acts of destruction, take pics of everything.
Second, sounds like two wires were repaired at the starter, right? You have a fifty fifty chance of getting it right. Not bad odds.
After reconnect, if your starter turns the motor over, you're good to go. If not, switch the two.
Kill switch is not a bad thing as long as you remember it's there.
