NB o2 sensor, help ident wires
alright, so i pulled 2 NB o2 sensors out of my old H-pipe before i put the turbo on, kept them in the junk drawer just in case. im gunna use them for the megasquirt temporarily until i can get a wideband.
plan on cutting the connector off and using a 4-pin molex (like on a computer) but the wiring is kinda odd. its got 2 black wires, a white wire, and a blue wire. i've read conflicting things about wiring on it.
i'm assuming that the 2 black wires are the heater wires... but i cant find any definitive answers?

ah sweet.
looking at it now, its really faded out, but it says Denso.
there was alot of conflicting info on the web on what wire was what. thanks for clearing that up. wiring it now. all thats left is getting the sensors wired up and setting up the fuse block. i'm trying to figure out a way i can share some of the sensor info so i can retain partial EEC-V control for things like Tach/Speed gauges, for now fuel pump control (until i go dual-pump sumped tank return) and Cruise control.

The O2 sensors have nothing to do with anything but fueling, and then only in closed loop operation--there are DTC code "switches" in the EECV tune that will let you turn the sensor monitoring off, and should block any MIL trigger from the "eek-5"...
