I have a wire ran from the primary o2 to the pin for the secondary and a keep throwing a sec code whats up? SHould i run the second o2?

 

just run it to the first pin or primary one and no code but ur car will run like *** had my b16 running like this and I was running rich and shitty

so if u don't want a code just wire the first one it should be coo unless the o2 is bad then it will throw a code again


and well I would just run two o2's on any obd0 set up

 

just convert to obd-1

 

well if is is throwing a code, i would check your wiring, i ran a wire from my input for my primary O2 sensor to my secondary sensor, and it worked fine, all i did was cut into the wire under the dash and run a swap one to the pin i put in c19, that should work fine
