LS swap in a 99 SI?

I want to put a 98 B18b long block into my SI. It is obd2a but comes with a obd1 ecu. I have the obd2b ecu conversion harness. What will I have to modify to make this work.

I need to get the car running asap and this is what I can aford right now. My b16a2 is out of commission.

There shouldn't be any problems...if you already have the obd2b ecu conversion harness then its all plug and play. The extra sensors that come witht he obd2a motor won't matter since your obd1 ecu won't recognize that they are there. Plug and Play YO!!!
