well my f90bt and harness and dash kit should be here friday and im pretty pumped to get the install started......while i was at the dealership today for an oil change i asked them where the vss could be found......they located the wheel speed sensor and said that is it......is this correct? should i trace the wheel speed sensor back to the eco and splice into that or just leave it alone.....wife says leave it alone and just be happy with GPS adjusting speed(or whatever the vss splice is needed for) anyone have any thoughts on this?

the wheel speed sensor is the same thing, you should be able to use it. if it doesn't work, just disconnect it.
