1975 Chevy C10 truck fuel gauge issues

[Chris Obert]

It's a long story, but after new side tanks and a new (later) valve to swap between the tanks, the fuel gauge is at the 3 o'clock position.
I have been unable to find an early 1975 wiring diagram for the original 5 terminal rocker switch. Do you have one?

You might try looking here:

Scroll down to "Wiring Manuals - 1975 Chevy", center diagram on page 6. Should be this one?

Thank you. I have printed it, and will get out my magnifier and look!
