I just wanted to know if anyone has ever run an on/off switch on their wideband gauge? I just got a innovative lc-1 with the db blue gauge. It seems kind of pointless to run the gauge all the time(i drive a lot on the highway) It looks like the gauge and the lc-1 are standalone units. So I would only be turning the gauge off and not the controller unit. Also what is best to switch? The positive or the ground? thanks in advance.
