OK… the part# being JDM NA engine cars might explain why I can’t find it listed, as the list I’m using covers all years of NA & TT engines for Eclipse, Talon, Laser, Galant, 3000GT, Stealth, but only covers TT engine versions of JDM not the NA engine cars. So sounds like your good as far as two ECU’s you have.
Here’s my take on the ECU’s condition, others may have a different view which I welcome as like most I’m not always correct. The first five pictures of what appears to be all black (unsure) capacitors looks to be all original capacitors, with the one nearest to the plug connectors obviously leaking. That would indicate all need replacing, board cleaned and inspected around the leaking one. The second five pictures of ECU with the one light-blue capacitor and three dark colored (dark brown maybe), the light-blue one has been replaced but the three dark colored ones look to be original. This indicates to me that at least the dark colored capacitors need to be replaced.
In summary I wouldn’t trust either for long working or not without first replacing the necessary capacitors, because if they haven’t failed already they will shortly. If I interrupted what you said correctly the ECU with all black capacitors (one leaking) is the operating ECU, I’d say consider yourself lucky because it’s not going to work for long.
