crx d16a9 b16a2 swap vtec dohc

hey guys looking for a bit of help as a cant seem to find a straight answer on the net.. at the end of the month im picking up a b16a2 to swap into my ed9 crx..the engine is running with an ek9 ecu and obd2a loom.. will the full obd2 loom work with my crx and is there any conversion harnesses...

after a majour bolt broke on the head of the current d16a9 iv decided to start looking into a b16a2 swap, looking for a list of essential parts il need, and if anyones done this swap or similar is there any issues i might run into? thanks in advance
