Hey guys, sorry to start another thread as I already had one below but hoping for responses here. I am all set to order a factory hitch from here: http://cgi.ebay.com/ebaymotors/NISS...542213QQ_trksidZp5197Q2em7QQitemZ360354349753 It says that it already has a 7pin connector for the wiring harness, is there anything else I need to purchase with this? Also does the factory unit accept a 2" ball mount? I have a Reese unit at my house that would work for me if I can use it. On another note anyone have experience with Performance Nissan parts.com? Thanks in advance.

edit: maybe link works now
