1G 90 cruise control 12v constant?

[Vic321]

I've read that the cruise control switch on a 90 has a 12v line rather than a ground. My question is can that 12v line be used as a power source for a wideband? Is that a constant 12v line? I don't have cruise control anymore so I'm setting up nlts in v3. Also if I were to move the cruise settings by the steering wheel on accident will that affect anything?

Even with it being a constant you want to stay away from tapping any accessories to a wideband for any gauges. I would recommend to tap right into the ignition 12V source for the least amount of problems.
