if you haven't already, download the service manual from the link above, just below the Bullxb.com header or from buellmods.com. in Appendix B of the service manual, there's step by step instructions on how to remove/install pins and connectors. it's not very hard at all, just take your time. also if you can get your hands on a parts catalog, that will help you out as well.
I didn't know that the connector had been updated, wish I could help further
