Has anyone installed a Dakota Digital SGI-100BT into their 1993 or 1994 80 Series?

Just got one of these puppies to calibrate my speedometer to 33" tires.

Has anyone used THIS interface? and if so, where did you find the correct wires and where did you install it?

Pics are worth a million words....

Thanks!!

I've used it on other trucks, very easy to use, wires are listed in the diagram.

lutz auto has a calibration module that plugs right into your speed sensor under the truck, it's about the same price.

Which diagram? The FSM doesn't indicate the vss wire

Did you connect the SGI-100BT behind the gauges, or at the ECU, or at the speed sensor on the TC?
