    So I compared an original non Rallye Satellite Dash cluster wiring harness with the Rally wiring harness I am installing. I ohm'ed out all the wires from one end to the other and all looks good. Other than the wires one would expect (headlight switch, heater/AC, etc), the biggest differences I see are ground wires. I see two ground wires for the non Rallye, one may have been added because it doesn't look original. I do not see ANY separate ground wires for the Rallye. Does this mean that the dash frame itself it what provides the grounding for that entire wiring harness? Or am I missing something incredibly simple but very important?

    Thanks in advance!!!

      You're bang on.
      Dash frame grounds the cluster housing but it's never a bad idea to add additional.

        I added another to the left screw clip where the dash screws in. Any other place recommended?

        I had same question a few months ago when I was finishing up the dash install. Took a continuity check from several screw holes to the negative post on the battery and it was connected. Whew!
