buy the one for the engine: Del Sol VTEC or 99-00 SI if it's OBD2. Now for the differences on placement of the O2 sensor, the only thing I can think of is for emission purposes. I see alot of LEV and ULEV cars these days have the O2 sensor right where the cat and exhaust mainfold becomes one. I guess they want the cat to have a quick start up instead of the ol' fashion slow light up like the mid 90-80's cars normally have.

then just use the O2 sensor from that year engine( I mean from the crx); the 1 wire.
