I had to. That was the only place I could find one. I don't remember exactly what it was called, but it's the pigtail that plugs in at the base of the shifter. It came with 6 wires, only 5 are needed, so I un-pinned the extra one. Do yourself a favor and solder the wires in instead of just crimping them. I ended up having to go back through and solder mine about 6 months after installing the pigtail with a crimp because one of the wiggled out.
