Access to the ECU and its connectors is easily achieved by removing the ashtray and reaching up and behind the ACC unit and popping it out. Unplug the unit only with the key off. The various sensors and motors in the interior are accessed by removal of the glovebox. The components in the engine compartment are accessed by removing the cover under the windshield (either 25 Torx or 8 mm hex depending on year)
