wideband power/ground

I have a innovative lc-1 wideband and a 94 civic ex. I hooked the simulated o2 signal to d14. I have been reading around a some people say to pull the power and ground from the ecu and others say go to the battery. What place would be the most accurate. Also what is the ecu's voltage limits for o2 signal. 0 to 3.5 volts?


Also I have a D15B in my car with a Moates ostrich and crome. I keep getting codes 20 and 36. 20 is the eld which I have tried turning off in crome and still get the code. But 36 is for traction control from what i have searched. My car has the stock p28 ecu without traction control. Any ideas of what it could be caused from



Thanks-Nick
