Re: gauge wiring

You have found the BROWN Alternator wire Circuit #25. Circuit #25 is not for any gauge and should not be wired to a gauge cluster.

Let's try to help you get your volt gauge working.

There should be three BLACK grounds. The "Instrument Cluster W/O Gauges" harness only has two so you need to add one for the volt gauge.
There should be three PINK ignition power wires. Again the "Instrument Cluster W/O Gauges" harness only has two so you need to find or add one for the volt gauge.



One BROWN wire is from the alternator. This wire/pin is Circuit #25.
Stub the BROWN #25 wire off @ 3in from the plug leaving enough of both pieces to connect them to additional wire.
Connect a 3ft chunk of black 18ga wire to the plug stub. Route this wire to a chassis ground.
Connect a 3ft chunk of (not black) 18ga wire to the harness stub. Route this wire through a 470 ohm 1/2 watt resistor to an ignition power source.

The other BROWN wire in your plug goes to the heater fan plug and fuse panel. This wire/pin is Circuit #50 it should give ignition power to your volt gauge.[/QUOTE]
