Im in the exact same position (93 DX 5spd.) I'm am just getting together all the honda OEM parts.

The list of parts I am getting are this:
CC actuator (under hood)
CC unit (computer under dash)
steering wheel buttons
brake/gas pedal assembly from a cruise controled civic.


The real thing that will make or break this project is how much of the wiring is alrready installed. If honda wired all the cars the same and just didn't put the components in, this will be a cinche. If none of the wiring is there this will be a real bitch to install.
