OK, that's what it looked like. LeafScan never made it to the masses, I guess. So sad. The OK press seems to be the one significant annoyance that nobody has addressed with a proper mod.
In the meantime... you again helped me install the "anytime camera" and the speed wire interrupt. Having you describe the proper pins is immensely valuable. Heck - just reminding which way around the diode goes is huge. (note that I just dug right back into the package of diodes that I purchased for the Prius mod. LOVE having all the pieces necessary here on the workbench.)
So there it is. Done without much fuss. And free. I also pulled power to the center console for the heated seats (looking for a console removal tutorial next!) And I mounted my LeafDD properly (was velcro'd crooked up in the eyebrow over the tree and signal indicator - now straight and magnetically attached above the center stack - pictures of that when adhesive sets and tape is off!
Thank you once again, keydiver. You rock.
