i'm willing to disconnect my rear o2 completely and connect a lc1 instead. is it a bad idea to use narrowband o2 12v+ and ground wires to power lc1? if yes, why? i think this way we could eliminate the whole hassle of getting to ECU.

 

I believe the wires that go to the rear 02 do not have a constant 12v+, the ECU turns it on and off which is NOT ideal for a wideband.

 

according to wiring manual it seems that it's +12 volts from the engine relay, am i wrong here? aren't it as constant as everything that powers the engine... did anyone do a research?
