I am interested in upgrading the interconnect using cores from Belden 89248 cable. Probably three twisted pairs woven together for a total of 6 cores. The factory setup has a pin connection and a blade connection. The blade is jumped to the black binding post (see photo). If I install a separate binding post for the new DIY interconnect, would I still need to worry about the blade connection? If the blade is only for structural integrity, then why is it connected to the black binding post? Sorry for my newbieness.
