My car is in limp mode and need to install the o2 sensor off my integra parts car that i got the 98 gsr motor from.

Need to know how and where to install the o2 sensor into my EG.

Have the p72 comp.
QUESTION#2 - Can i attach wires to after cat plug and extend wires.
And or do i need to switch the secondary plug into the cat and add wires to go into the secondary..

also have CEL CODES

1. 54 - CKF - crank fluctuation sensor
2. 65 - Secondary oxygen sensor heater wire (black wires)
3. 3 - MAP - manifold absolute pressure sensor
4. 22 -VTEC pressure valve

and do not have vtec plugged in yet- Might have map and crank sensor plugged in wrong.

 

the crank sensor will cause the limp mode, and can you re-word your 2nd question? since your using a obd2a/b ecu, then you will need a O2 sensor after the cat, just connect it to the factory wiring
