Yeah that's what I meant. Older Civics had a one wire o2 sensor, you would just hook it to that one. My 97 EX had a 3 or 4 wire one, don't remember exactly, but I found out with a voltmeter.

Yeah mine had a 4 and I hooked it to the white wire coming off the O2. Or you could look up the pinouts of the ecu and tap the 02 wire there.
