I'm trying to tie a Pioneer AVIC-8100NEX into the VSS on the Mark. It shows it's pin 58 (GREY/bk) on the PCM (VSS+) but when I hook it to the Pioneer it still doesn't see it as the VSS. For the fun of it when I "unspliced" the gr/bk wire I left it disconnected and took a drive. My speedo still worked... I'm like so confused. I read on another Mark VIII forum it also can be the DG/Y on the passenger side because it ties to the GREY/BK on the PCM. The schematic does show this but... Does anyone have any idea which is the correct wire?
