I have a 2005 E450 Ford Econoline that my RV is built on. It has a 10 cylinder engine and 4 speed automatic transmission. I need to locate the speed sensor wire so that I can install a GPS system into it. Does anyone know where I can locate this wire without tearing out the dash to get to the back of the speedometer?

Thanks your your help

i am not certain of that particular model, but it would either be in the rear dif housing, or the tranny..i dont believe that they used wheel speed sensors.
