GM O2 sensor?
Hi,
I'm trying to use a bosch universal sensor as a GM replacement for their Denso unit and I need to splice in the old denso connector. That saves me 100 bucks! Problem is Wire colors are different. How do I figure out which wire is the trigger? Can I assume that the two same color wires are the heater and thus no polarity, AND if one of the other 2 wires left ground to the case of the O2 sensor then the other wire must be the trigger?
gm wires are 2 blacks , 1 white , 1 blue
universal wires are 2 white, 1 black, 1 grey
Thanks Guys
