I just swapped a 96 B18b LS motor into my 95 hatch. Trying to figure out where my O2 sensor plugs into...i'm using the one off of my dx motor..I believe it's a 4-wire.....looks like i'm gonna have to extend the wires since it will be at the end of the header but don't see the plug on the enging wiring harness where it's suppose to plug into...what are my options?? am I gonna have to wire it up straight to my ecu??

Since the O2 sensor on your EG is in the rear by the cat, you're going to have to cut and splice so that you have wire long enough to reach the O2 sensor on the EG, which like you stated, is in the front on the header. Any kind of wire is acceptable for splicing unless you want a clean look. I've seen speaker wire used to extend the O2 sensor before. Good Luck!

Since it was an OBD2 wiring harness I just used the secondary O2 sensor plug found in the rear of the motor.....I was looking back there and noticed it hanging so I plugged in the O2 sensor and screwed it in the header and it was perfect cuz I didn't have to extend the wires! And no codes or anything!
