1986 Nissan 300 - 96,xxxx miles, 5 spd. brand new fully charged battery
would go dead in about 1.5 days. -
with car parked, engine off, doors closed, key Not in ignition, - parked
status-, I put amp meter on.
something pulls 2 amps from battery with everything off. car previously
had right front side damage - front and right fender were replaced.

have been trying to trace down where the fault is. pulled all fuses, etc
to try to isolate draw.

just forward of battery is a small junction box with 4 jumpers/connectors.
If I unplug the far left connector -- labeled EGI INJ (BR) -- amp draw
drops to .05 amps.
If I unplug the far right connector -- labeled BAT (b) - amp draw drops to
0.0 amps.

looking for suggestions and or wiring schematic for car.

thanks in advance..

Try unplugging the alternator. A bad alt with a leaky diode will do that.
