Ok...mostly got the n2 installed. I tapped the pink/black wire in the small radio connector, and for some reason I don't get a speed pulse.
I didn't want to pull the drivers a-pillar off cause there is an airbag in there, but I looked under the dash, got the harness that goes up to thru the a-pillar, I only saw a light brown wire, tapped that (what a pain...) and my n2 didn't see the car as in reverse.
But my slope works now..somehow
hmm...
