Stock Volt Gauge, Which wire?

[PsRumors]

'85 Suburban, stock GAUGES. I pulled the 350 out and put in a 454. I have everything working other than the Volt gauge. It shows 0 volts.

Where does it get it's reading? The only thing that has changed, other than the engine, is I did a remote solenoid. I did this due to the fact I hate all the wires running down to the starter, along with the fusable links.

I know I have power and I have done a load test on the battery and at charge the alternator is putting out 14.4 volts.

I just want the gauge working.

TIA

Volt gauge reads from the instrument panel printed circuit IIRC. Same voltage that feeds the other gauges. If it's not from the printed circuit itself, it would be from the fuse panel.

You DID somehow fuse the power leads you changed though, right?

I didn't change any power leads. I used the stock leads to activate the aftermarket solenoid.
