Started what I thought was a simple project. Replace rubber lines with Stainless Steel. 2001 360 F1 spider. Went to remove passenger side inner wheel well panels. Unlike my 355 there are attachments on the upper section. Vacuum Tank and electrical connector. Vacuum tank removed. Stumped by electrical connector. Nut turns with bracket. Attached? Hidden so difficult to see how to disconnect from the rectangular connection point. Any help greatly appreciated!
