oxygen sensor wiring diagram
oxygen sensor wiring diagram Sorry to ask this again, but I have an 02 camaro SS pullout (t56 if that matters) and front 00 camaro ss oxygen sensors. The wiring on the harness looks to be black, red?, orange?, lt yellow. The oxygen sensor is tan, tan, light tan/pink?, purple. Can I get a diagram or any help on this? I posted in the newbie section, but was hoping posting it here would help it get to some new faces. I am extending the wires myself and I am trying to find something that tells me either which wire goes where or at least something on the o2 sensors (which wire is sigH, sigL, ground, ign).

Found this... which was helpful: http://sparkplugs.com/glossaryImage.asp?imgID=328
Im guessing its the Violet (purple), brn, brn, pink that I am looking at on the oxygen sensor. With:
Violet/Purple = Sig+
Pink = Sig-
BRN = HTR
BRN = HTR
if anyone can just tell me which to hook these up to on the factory harness or a diagram or similar that'd be huge. I cannot find a dang wiring diagram for the factory side anywhere (02 camaro ss).

from your wiring harness
Pink +12v
Black ground for heater
Purple - signal high +
tan - signal low -
So your wiring from ENGINE HARNESS to O2 SENSOR would be as folows.
pink - brown
black - brown
purple - purple
tan - pink

my eyes are apparently crap or light bad or something... Those colors don't match at all to what I saw on the harness last night, but it may just be from heat/wear/fade or something... Thanks for the help
They should. Colors didnt change until much later than the Fbody's were produced
Drivers side O2s were tan or ppl with a white stripe
Pass side solid tan or ppl
IGN/grd wires were solid regardless of bank

You were absolutely right. I am just blind. When I put a better light to it the colors were right as shown above. Thanks! Wired up and she drives great.
