Hello, my name is***** you take a picture of the terminals? Thanks.
Either one should work fine, it is setup like that incase wire will only reach one side. Stands for right and left. Let me know if you have more questions. Thanks.
You probably blew a fuse. With meter or test light the large wire should have voltage at all times and small wire should have voltage with key in start position. Let me know which one is missing, thanks.
