ECM is from suzuki Samurai part. no 33920-B0C70 bord number is E331A973A

Thanks
well that is easy
that cap love to fail and are best and cheap at mouser.com 105C temp spec

it cover this on my ecu page fully
i will  now quote my page

[*]LOW ESR or Low impedance (both mean the same) Nichicon UPJ is the best. (IMO) (impedance , is A.C resistance)
[*]Higher voltage is ok, , 47uf is same as 50uf. ( if you go too high in volts, the top of cap may hit the ECU lid, so be careful)
[*]Highest range of temperature, is the most important in cars. -55 to +105C is best


Here is the most common cap to fail (pre 1996 cars) is high temperature rated use 56uf/63vdc.  [url=http://www.mouser.com/Passive-Components/Capacitors/Aluminum-Electrolytic-Capacitors/_/N-75hqtZscv7?P=1z0wqufZ1z0z7l5Z1yyc4mbZ1z0vhz5&Keyword=nichicon&FS=True][/url] (the original might be 50uf and volts 50v)
RADIAL caps (bottom pins.
near 50UF
near or over 50vdc rated
105C
and top brands not from noname china.

a whopping, hold your hat  79cents

my page is 14 year old now, ouch time flies.

the cap is brute force power filter, cap, to keep cars NOISE (elect) out of ECU and worse the ECU VRM.
low ESR is best.
