There is no main relay. The power runs from the battery to the starter where the primary power lead crosses the engine bay to join the alternator lead before splitting to the Hi speed blower relay and (fusible link) thru the bulkhead where it divides off to the ignition switch, headlight switch, horn relay and fusebox. The ignition switch supplies "keyed" hot while the other branches are always hot. The always hot circuit coming out of the fusebox is mainly orange.
