I'm trying to install the Grom Vline2, and need to tap into the reverse wire. However, Grom's instructions (photo below) do not look like my connection. I'm supposed to find the 28-pin connector. In their instructions, they show pin 1 at the top left and pin 28 at the bottom right. My connection (photos attached) appears to be backwards, with pin 1 at the top right and pin 28 at the bottom left. Grom's instructions don't line up with either the colors that I see, nor configuration of wires and empty pins. To complicate things more, as I look at a schematic of Acura TL's wiring (photo attached), their 28-pin connector (unit with Navigation) doesn't look like my connector either.
I've reached out to Grom support, but I thought I might try here to see if someone responded more quickly than Grom. Thanks for any insight you might have! 28-pin connector rear, view 2 28-pin connector rear, view 1 28-pin connector front Grom's instruction to tap into the reverse wire 2012 TL wiring schematic
After contacting GROM tech support, I learned the answer to this issue (which was rather complicated). I explain the answer in my installation video, located here:
