if its not a wideband its pointless to hook it up... its just a pulse reader not a true A/F ratio reader...

But to the answer yes you can but it will not do anything but read the pulse.... so if your trying to look cool go ahead. use the purple wire to the O2 sensor, I think it will be the Green or Gray wire you need to use, not the black,. your black off the gauge is for any real ground , and the red is a constant power use the radio fuse
