Peter,
its not an import as far as i know, go to your insight...there is a small "2cm blue" plug with brown and black wire going into a secure socket of plastic also blue. just pull it out. i believe all hondas have it. you just have to know it.
Its NOT on the ODBII port....its under your glove compartment box.
it looks similar to this one:

FYI i got another car a honda "odyssey"
