i've searched and havent found any specific info. what i need are the info on the requirements of getting bar'd. what the refs look for and the whole obd1 and obd2 issue.

vehicle info: '94 civic dx.
plan to swap in a obd2 b18b motor with harness config to obd1. the intake manifold is off an obd1 motor. i have the obd2 intake manifold with harness.

would i need to modify my civic harness to be obd2 ready? ecu harness too?
should i use the carbon canister from the integra or use the civic's?

tia guys
