I'm trying to install a Pioneer F90bt in a 2001 Tahoe. I can't figure out what to hook the pink speed sensor cable too and the purple reverse gear signal output wire? These are the only 2 things holding me back. It doesn't say how to do it installation manual because I guess it's different for all cars? Pioneer says the Navigation might not be accurate without these wires. Someone PLEASE HELP!!!!!//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
