I just installed a new engine in my FB, it's an 83. For the life of me I cannot figure out which terminal on my starter is 'A' and which is 'B'. Then there is that additional wire, it has a loop also, I have forgotten which terminal it goes to.

 

The small wire goes to the solenoid (sp). I know that the power has a ring and is the larger gauge wire. I think that the ground has a different attachment. I cant remember though. I will have to look. Hopefully someone will chime in with the rest of the info you need

 

Battery power goes to the terminal furthest from the trans and the ground to the terminal closest to the trans.

 

thanks! It cranks again, now for the timing. lol
