Very interesting, you're definitely correct, my mistake!!! I've never heard of this before, and just for kicks I checked the old Q's. To answer your question, the condenser is on connector F23, and the ECM relay is on connector F66. I'm looking at the wiring diagram on page EC-402. You can see where those connectors are on page EL-508.
Of course, the term condenser and capacitor are synonymous, so really the only thing it's doing is stabilizing the circuit so as the coils are firing there isn't a power drop as they fire.
In any case, if you're tracing a multi-cylinder misfire the most common cause is the ignition coils. They seem to be temperamental, in that they will be intermittent if they're warm or cold. There doesn't seem to be a lot of rhyme or reason.
