There are two electrical 'black boxes' in the '81- One is inside the
cabin and is usually on the under tray by the passenger side. It handles
care and feeding of the O2 sensor and stuff.

The thing you're ref'ing is the electrical ignition module, located up
in the rain tray and near the wiper linkage. Some cars (California &
smog equipped I think) have an additional box there to; a Digital Idle
Stabilizer. It is removed and the two plugs connected together during
tune up and testing and reinserted when done.

The Hall Sensor is built into the Distributor. It has a female connector
that pokes out the side and some cables plug into. Often the wires under
the cap will get all toasty and brittle. In mine the car ran worse and
worse until it wouldn't run no more. I tested the wires with a meter
only to get fooled by connectivity- the would pass electricity but not
enough to register a proper signal, the same then as no signal at all.

The signal to the coil is pulsed, at least that's what I think also. I
gota run to work but I think it's the Hall signal that's providing the
signal.

See ya,
