My instructions from Rywire on their harness for the b16 are:

O2 sensor-
1) brown wire to black 02 sensor
2) purple to green O2 sensor
3) yellow to black o2
4 grey to white o2

Black to vtec solenoid (1 wire square shaped plug)

Green to VTEC pressure switch (below the vtec solenoid) blue wire
The othe wire just needs good ground (plug is green and round with 2 pins)

White wire to one wire knock sensor (1 pin plug above oil filter)
