76 duster gauges not working

[chargers777]

Which color wire is the power wire going in to the circle connector on the gauge cluster ?Which fuse powers it? No fuses blown and I grounded the fuel sending unit wire and the gas gauge doesn't move.

I have a poor home made copy, and the 76 printed manual I had HAD is gone after the house fire. You need to scare up a legit copy of a factory service manual for your car, either digital or paper. the wiring diagrams are difficult

Here at index 51 or 51 B or C, power comes to the IVR on the PC board trace to the harness connector C1-10, from wire G5-20DBL (Wire no. G5, 20 gauge, Dark BLue)

Shows that wire at C1-24 maybe fuse 5?

There are a dozen or more Chrysler electrical service manuals on eBay for less than $20.00.
Here is one example
