I now see from the schematic that this plug is for the tach so I tried polarity until it was correct, I had to fab my own small female bullet connectors for the pins.
Now all the gauges (except speedo) work as they should as long as I dont bump the cluster wrong and make them all erratic. Maybe thats just a ground?
The electric speedo is still dead. I hate electricity so very much. I'll do more searching on the speedo and instrumentation illumination but if anyone has any wisdom please feel free to bring it forth!
