It has two holes. One to put on the small (battery) post and the other end to hook the normal wires....oh, and it has a Black ground wire to go behind the nut that holds the guage in the dash.
Here is a pic... don't laugh at my temporary pigtails...I may even decide to do a "quick disconnect" in case I have to pull the guages. I'm to old to stay bent under there to long!!
