i have a 96 ek swap a 99 b16a2 with a 98 ex harness, I have trouble wire the second o2 sensor at the back of the cat converter. There four wire, i finger out the three wire, but i don't know the last wire. hope the picture in the bottom help.

 

jl;

 

looks like it could be connector "D" pins 23 or 24

 

but connecter d don't have pin 23-24

which is the last wire your having trouble with? black, white, or green wire on the o2?

 

i am having the same issue.... this is what i did:

Green (ground wire) went to D13
White (signal wire) went to D14
Black (heater wires) went to A5

originally i ran both of the black heater wires to A5, but read somewhere that one of them needed to be grounded. Tried that, and still got the CEL. if somebody could just spell it out, it would be greatly appreciated. maybe just like:

green wire = x1
white wire = x2
black wire1 = x4
black wire2 = x5

this is because i am a wiring retard, and need it spelled out like this?? help pls!

I finally figured out how to fix this, and wrote a post on it.
