Dash Harness ?

I think I looked at the 70 manual and they don't show a Ralleye dash. I bet it's close if not exact. The sensor wiring had not changed for years. if you can post a good clear photo of the rear of your cluster, "we" can follow the circuits visually. They are easy to figure out.

Another thing to be careful of is connector numbering. In addition to numbering the skipped pins, you are looking at the rear of the cluster, clockwise from the key. So the harness is same, you are looking down as if it's connected to the cluster.
