I have 02 WRX, manual. I purchased the car without starter. I purchased one and I am trying to put it in but I am confused what to do with the wires. I have positive from the battery, negative with a wierd metal 90 degree metal peice and a small black connector(I figured that one). I looked at the starter wiring diagram and it only shows positive going to it. Any help would be grately appreciated. Thanks!
