Short of actually seeing it, I can give you a verbal. The two big terminals are the high current ones. Connect one to the battery, the other tho the big lug on the starter. Of the small terminals, one gets grounded (chassis) the other goes to the start terminal on the key switch or start button or whatever you have. Basically, you complete the circuit on the small terminals, which pulls the plunger and connects the large ones together. USUALLY it doesn't matter which big terminal is which, or which small terminal is which.
