i have abunch of added crap on mine, couple relays for fuel pump, water pump, etc. i have the stud under the fuse box cover with a couple ring terminals on it. one of them is switched the other is always hot iirc.Ordered that obd aem wide band. Where did you power yours? I'm assuming add a fuse but which one and where did you source power?
i think i originally just tapped off the cig lighter circuit but mine stay hot all the time and (my) wideband if energized goes into heating mode if its on and not up to temp (doesnt know it isnt running i guess) and as long as mine would sit it was enough to kill the battery after a couple weeks...soo uh dont do that. it doesnt use jack shit for power i wouldnt worry about tapping it with any switched source really
