Need help with speedometer

[Madera]

My speedo took a sh-t.  I bought a Dakota digital unit and need some advice.
(98 Standard). The standard is mechanical. Do you know what I will need to
make this unit work??  Do I need an interstate sending unit at the wheel?
Will the interstate unit send the right signal to the dakota? Iwould like some
advice PLEASE...........Thank you in advance     Madera

Contact Dakota, they know their products, better than any one here I assume.

I run a Dakota volt meter on my Trike and they were more than helpful over the phone.
