Connecting Innovate LC-1 Wideband

[Tarantula]

I am buying the LC-1 and heard that there are several ground wires. I wanted to know what others have done. Where did you connect each wire. Also I wanted to log the wideband results on the logger. I felt the best way would be to use the second O2 sensor input wire. But would that set off a CEL? Any help would be appreciated.

You are best off placing the analog and digital grounds on the same grounding point as the ECU, but you can just just put them all to one grounding point that is very clean. You would be best off to use a ohm meter to check your grounds and get them to under 1 ohm. Do not tie the 3 ground together and add a piece of cable to a single ground. Although it seems like your doing the same thing as putting 3 ground to one point you are not. You can end up with ground loop interferance that can easily be seen on a scope. I try to scope all my grounds on a new PCM install just to see how clean my grounds are as they are the most important for your computers to operate correctly.
