Hi i have a 2000 Honda civic with a b16a2 swap. From what i read i have to extend the secondary o2 and wire it directly to the ecu? If not then how do hook it up?

 

What is the trim of your car? Ex,DX,lx,hx? What engine harness are you using?

 

Its a ex but i have the correct engine harness. The secondary o2 sensor plug is on the cabin harness

 

Ok so you shouldn't have to wire it in because it's already there.

 

Well the way my catalytic converter is set up the o2 sensor hits the shift linkage so it is bent and could be broken but whenever i connect it my spedo fuse blows when it warms up and it throws 3 more codes.

 

Bump. Anyone know why when i connect the secondary o2 my spedo stops working?

 

You're shorting something to ground.

 

Should i have continuity from fuse 15 to the green wire on my o2 sensor?

 

Here’s the pin locations:
OBD2a
2nd 02 Sensor ECU Connector
White Wire TO D14 – Sensor Heater 02 Signal (SH02S)
Green Wire TO D11 – Sensor Ground 2 (SG2)
Black Wire TO A5 – Secondary Heater 02 Control (S02HTC)
Black Wire TO A11 – Power Source 1 (1GP1)

 

I dont have a D connector. Only A, B and C. Ill probably just use a continuity tester to see where they go. I think i know though
