the b16a2 were used in euro market from 92-95 in vti and were obd1.also used in the 99-00 si usdm but I think it was a3 cuz when i order parts from honda the book they use list it as b16a3 just like the usdm delsol.so on that note if you need a harness you can look to the edm cuz those are left hand drive obd1 that will work but when I swapped my motor I used the vx harness ang only had the o2 and egr clips to deal witheverything else matchedand plugged right in rewire the o2 and run you wire for the vtec,knock sensor and you should be golden but check out hybrid-honda to make sure that is all.
