There are no pins on the mirror side , but on the harness side there are pins, I just spliced the wires twisted them into the empty mirror side pin holes, and when I connected the two connectors (mirror side/connector side) together they made contact. I don not know where you would get the pins from since no one sells them or for that matter makes them.
