To err is human, to forgive your mercy.

In case of an ECU for a 1996 JDM Celsior, following 9 capacitors are used
C101 10uf 50v
C102 10uf 50v
C120 100uf 10v
C121 100uf 10v
C141 220uf 16v
C781 47uf 63v
C804 15uf 35v
C805 15uf 35v
C831 47uf 63v

Some may be different but most of these are similar to yours.
Due to the Californian smog regulation, the ECU is different from federal ones and I believe the ECU uses more capacitors than federal ones.
