Installed my LC-2 on the rear O2 port today.
At first I tried using the power and ground ports on the plug to power the whole thing. However, it seems it shares a ground with the throttle body. When I powered it up, as soon as the O2 heater turned on, the throttle body freaked out.
The LC-2 must be pumping a ton of noise across it's ground. I ended up running dedicated power and ground for it, and it seems fine now.
Just something to be aware of. Other wideband setups may be fine, I dunno.
