I have a 2007 Highlander hybrid....connected my unit to pin 17/yellow on the second plug from ecu behind glove box, but the gps went all crazy jumping around.....does anyone know for sure where the VSS wire is in this vehicle? alternative option is to have the Speed Pulse message removed....the freakin thing is blocking the gps top portion of the screen which has the most vital information. any help would be greatly appreciated
