Switched and unswitched power sources - Interior

[FRED]

Ferocious is right about the seat belt. See page W-1 of the series five wiring manuals onlin.

Battery buss in the interior fuse box: defroster, heater, stoplights, room antenna, illumination, ABS, SEATBELTS, fog. All hot without the key in the ignition.

IG1 fuses: engine, meter, antenna, power window, turn. All require key to ON or better.

IG2 fuses: wipers, cooling fan, rear wipers. Power when key is ON and no power if the key is HELD to START.

ACC fuses: audio and cigar. Key to ON or in ACC. No power if key is held to Start.

No real excuse other than mostly looking at series four interior fuse boxes and those boxes are divided up much like I suggested in my jpg attached in my first post. Seems the only thing wrong with that jpg is I should wrap a red line around the ABS, seatbelts and fog fuses to indicate they are on the batt buss and NOT on the ACC buss. For some reason I can't make attachments to day on this forum.

Anyway on page W-1 of the 1991 wiring manual online, they show pretty clearly what fuse is on a batt bus and which is on IG1, IG2 and ACC busses. In other words which is switched power (IG1, IG2 and ACC and fixed power or batt power 24/7 on the batt buss (items fed from the BTN fuse in the engine bay on a W/R wire).
