Add DIC to SSV ?

... also has that "realtime" V8 economy display that shows current fuel MpG. I am always laughing when it shows 99MpG ...

When your foot is off the go pedal,
and the pcm / ecm determines the road is driving the powertrain thru the wheels
(instead of the other way round)
the pcm /ecm temporarily engages Decel Fuel Cut Off.
On a long enough downhill / tailwind, engine coolant temp would get low enough to
cancel DFCO, but until then, or driver cancels it, or road speed gets too low, yes indeed, 99MpG.

Is the wiring harness on the right side of the steering wheel in a 2012 Tahoe PPV?

Yes. Behind the trim in that cavity visible just behind the DIC switch I’m holding.

Yeah it does all kind of engine and transmission stats.. interesting. It also has that "realtime" V8 economy display that shows the current fuel consumption. I am always laughing when it shows 99mpg ... yeah right ... I think my Tahoe does 15mpg, on long hauls on average.

99 is real when you’re going downhill with your foot off the accelerator. I get 14.7 average also but I get 20 mpg at 80 mph.

Don't forget to change your pronouns after you install your new DIC.
