Hey f body legends, i may be posting this in the wrong forum, if so please move. I have a simple question, im installing a flip out dvd/navi screen in the car. For the navigation part to work accurately, it needs to be connected to the speed sensor wire. I know it runs off the trans, but where does it end up, under dash? at the pcm? I need to tap into it, any help will b appreciated, thanks guy.

 

I am also interested...I know it eventually goes to the speedo, but the PCM uses it as well I think.
