Use the dash wiring from the integra.. there are a few write ups on here and honda-tech on how to do it.. for the carpet, use the civic carpet.. its premolded from the factory, and the integra carpet will have gaps and look goofy. As for the door panels, they WILL fit with some modification.. you will need to relocate the interior door handles and use the interior handle linkage bars from the integra to get them to fit correctly.. dont do the dash conversion without the integra panels.. it looks GHETTO.
