Intellitronics dash for 70-76 A body!

It's just like any other aftermarket Dakota digital or something like that. They send you a unit that screws in to your transmission or in my case the transfer case just like your cable does except for it's a little module with wires coming out of it... You connect those wires to the accommodating wires in the gauges.. and then from there you do a calibration where you have a friend with a GPS in the passenger side and he says go and you push a button and then he says one mile at a certain speed like 55 on the freeway and you push the button again....
And if for some reason you don't have the typical GM Mopar Volkswagen outlet and you have a Ford just tell them and they send you the Ford module...
This is the only way they can deal with all the different gearings tire sizes and so forth..
