There is ONE ground point for everything in the dash (which is a poor design). I'm pretty sure that includes the electronics under the dash. It's a 6 pronged connector up above the parking brake mechanism. It's slightly different from one truck to another, but it's in that neighborhood.

Also check continuity on that light blue wire.
