Hello,
Kind of a dumb question, I am trying to figure out some wiring issues and wanted to know which wire powers the RPM/Speedo gauge.(Image Below) As after putting in a new cluster they still refuse to work. Any help is greatly appreciated Thanks.

I'm not sure what the picture shows, that link isn't working for me.
Do you have the '83 ETM? Here's the best collection. The speedo diagram is on page 118 of my copy, signal is the brown wire with red stripe into pin 10 of connector C2. There's a "floating" ground too, brown wire from pin 19 of C2. Both those wires feed directly to the speedo sensor in the diff cover.
Save the manuals!
