95accordlx

Need help. I am puttin a 98 H22A into my 95 accord. THe 98 is obd2 and my car is obd1. Atomic performnace sells an adapter so i can plug the prelude ecu into the accord harness. WHat am i going to have to do about the obd2 sensors. The engine is comming complete with everything. So i know the engine is going to be wired fine. But what about the o2 sensor on the cat. Am i going to have to get a hole drilled in mine? IS there anything else i need to look out for?

Thanks!
