Re: 99 SI question. (RSX2SIcivic)
you should be able to use your oe wiring harness. The ecu you want is the p72. because it is an si everything else between the b18c1 and b16 setup is the same, the p72 has the most aggressive fuel and ignition map tho.... Have fun 
its actually a very easy swap to do!!
