I know of no relay called the brake relay and I was a Ford tech for 25 years

It is over your kick pad driver side in the corner onderniet your cover

If you mean to ask where is the heater blower motor fuse, it should be with the other cabin fuses, main fuse box, drivers side under the dash.

The heater itself has no fuse.

There is another fuse box in the engine compartment for all of the larger component fuses, like the cabin power supply, relays etc.

You can bypass the heater coil by unhooking it from the raidator or just take out the thermostat which is located in the neck of the water pump

On the drivers side by your left foot for the internal accessories, and under the hood by the battery below the power brake booster. Hard to get to sometimes although in plain sight.

Unfortunately Ford doesn't supply a download for guides older than 1996.
If the changes were minor (they often are), the '96 version should help:
1996 E350 manual

Instead of spending $20.00 on the 1993 ford wagon fix it book check by the fuse panel under the steering wheel or on the foot well of the passenger side. If none available the look on line at ford parts type in make and model and look for diagrams of the fuse panel.

There are two fuse panels, or power distribution boxes. The engine compartment power distribution box is located on the left hand side of the engine compartment above the wheel well, and the central (inside) power distribution box is located under the LH side of the dash, left of the steering column.

If the E250 is the Econoline/club wagon, then fuse box is to the left of the steering wheel under the dash.
