There are 3 open connections on the engine and I dont know which one goes to which post on the starter. One is a thicker bolt, but the other 2 are identical. Which one goes where?|||your battery positive cable goes to the large stud as well as another red 10 gauge wire which comes from your engine harness.
You should have a smaller yellow with red stripe wire that goes to the small stud towards motor
The outside small stud should have a purple ignition wire going to it but some motors the stud is not used.
A little more info on what engine it is would be more helpful|||You%26#039;ll need to be a bit more specific to get a reasonable answer.
