No such thing as a 'main' relay.

Under the dashboard,looking up from the brake pedal,there is a rectangular brown box about 1.5"Hx2"W with these letters on it: Mitsuba Relay assy.Main RZ-0088 12V JapanListen to the click when ignition key is on and another click about couple seconds after that.Hope this helps.
