Anyone install one of these guages? Do you know which wire is the o2 sensor input wire that your supposed to connect the guage too? i have 2 whites, a black and a grey. THanks
The black wire is the sensor wire. But it is easier to tap into the PCM harness.
Pin number 87 at PCM, red w/black stripe or Pin number 60, gray w/light blue stripe.
Yes, one is for the left, one is for the right, but I don't remember which is which. I had mine hooked up to a switch to switch between the two. It was really just a way to see if the o2's were working. The guage isn't much use for anything other than that.
If you want wideband for cheap (yet still accurate) and wanna keep your autometer gauge, checkout the Innovate LC-1. I just picked mine up for 179.99 over at DynoTuneNitrous.com, good guys over there.
