Testing gauges with new voltage limiter

There were slight differences in rally dash wiring in 67-9 cudas, that may be the case with yours also.
Unfortunately, I don't have a FSM for the Rallye dash. I do have one on CD for my Duster, but it doesn't include a wiring diagram for the Rallye dash. I have ordered a color wiring diagram specific to the Rallye dash, just waiting for it to arrive.
