An electrical connector may include a connector body having a passageway therethrough with a first end for receiving therein an electrical bushing insert, and a second end for receiving therein an electrical conductor. The connector body may have an outer end portion adjacent the first end of the passageway being movable between an unseated position and a seated position, and the connector body may also include indicia on an outer end portion that has a visibility changing to indicate the seated position. The indicia may take the form of a colored band. The outer end portion may move to the flared shape upon abutting the shoulder of the electrical bushing insert. When properly seated, the indicia will be visible to the technician looking down along the axis of the electrical bushing insert and first connector end.
