dont use the fuse box, under the kick panel there is a power block... you want the bottom most block, I believe the sticker is black for it

I was wondering... since we have a dual exhaust, would we have to have 2 wideband sensors to get a reading that is accurate enough to tune on or will one sensor be enough? also, does it matter if it goes on the driver or passenger side downpipe?

hhhmmm I had mine tapped in to the fuse box. I wonder if that is why it wouldn't calibrate properly...

Two would be good, but you really only need one. Mine is on the passenger side
