I'm attempting to get a boat going. I am replacing the solenoid. there are two big wires: a red and a black. 3 smaller black wires, 1 small yellow, 1 small red. I believe the two large wires go on the large posts (batt power and the cable to the starter) but I don't have a clue how to arrange the smaller black wires on the other posts. Any help would be appreciated. Thanks!!
