Mini Starter wiring help needed

[LongSixEight]

Im switching to a mini starter on the new motor and Im not sure which starter wire to eliminate to the starter solenoid since the mini only has one terminal. Do I get rid of the wire on the left or right looking at a stock starter from the front of the truck. I had a red on the left and a black on the right. Any help would be appreciated. This is all im lacking to fire up the new motor.
