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!!!
