Alright guys, I got the jumper harness from StreetLightz and I plugged it in. It worked! Now i'm trying to wire up the vtec and the O2 sensor.

On the O2 sensor, it has 2 black 1 blue and 1 white wires. Are the 2 black grounds?

is this an oem sensor or a universal replacement? they usually come with wiring instructions my friend...
 
it was a universal replacement. Thats why Im having trouble cause, the wiring color is different from the ones on the instructions.
 
The black wires are the heater wires, run acc/ign +12v to these. the blue wire is the sensor ground, and the white wire is the sensor output.
