Identification & application notes

Original title 'Civic EK3' is not supported by the exact part catalogue; publish Civic SiR 4AT with chassis verification rather than EK3 certainty.
Honda official 1995 Japanese specification associates Civic SiR/EK4 with B16A, but part catalogue does not explicitly identify engine/chassis; avoid inferring donor from the SiR name alone.
Photographed Oki label explicitly reads AT CONTROL UNIT, so this is not an engine ECU.
