Except power antenna. Note: These cables contain a series capacitor, which reduces the antenna system's capacitance. This causes the antenna system capacity to fall within a range acceptable to the Delco radio receiver. Caution: Do Not pass any current through the antenna cable, as you may short out the capacitor, leaving the cable inoperative! (Continuity must be checked with an instrument that measures capacity, Not an Ohmmeter)Once the cable is installed, removal may cause the female contact to become disengaged from the cable. In this occurs, carefully tuck the conductor wire and contact back in place. Do Not be alarmed by extra conductor wire, some slack is normally provided to allow for cables that are stretched during installation. NOTE: This 1969-1974E antenna cable was run under the dash, under the drivers side sill plate, over the wheel well, and back to antenna.
