An electrical connector (100) includes an insulative housing (40) and a terminal module (10) retained in the insulative housing and configured with a selected terminal (11), a determined terminal (12) and a specific terminal (13) molded within a dielectric wafer (2). A coupling lead-frame (3) is disposed onto a surface of the dielectric wafer and has its main portion (3a) parallel and aligned with the specific terminal. The coupling lead-frame includes one pin leg (311) crossing over the determined terminal and having a physical and electrical engagement with the selected terminal so as to establish an electrical coupling between the selected terminal and the specific terminal.
