Re: 1985 sport wrangler
Glad to help. What type of motor is it? Make/Model/year.
That is more important to helping you than the boat type.
To summarize there are normally 3 lugs. one is "B" or battery, one is ignition "I", which is on when you turn the key 1 click. the third is "S" or start, which is the momentary switch which activates the starter.
