Installing 1970 Mustang Gauges in my bump

The big trucks have the same connector options as our trucks, meaning that the earlier ones have the same connector with wires on the instrument panel and the later ones have the NEWER style connector and/for the printed circuit board type instrument panel. So do check that you get the right one or get part of the wiring harness from the truck so that you can wire it up to your truck.
The gauges will all work the same as the originals in your truck so your new sensors for gauges are all good.

Here is a picture of mine when I used the newer style in my 69 and just adapted the old wire harness connector from the old cluster to the new one using part of the wire harness from the big truck.
