Fuel Gauge Wiring

[shaolin.138]

Hey Guys,


Almost have the new speedhut gauges wired in. My last missing piece is the fuel gauge. Can I simply splice into the wires in the stock cluster, or do I need to splice further back by the fuel tank? If the first one will fly, which wires do what on the stock gauge for a 1971 Cutlass?


Thanks!

You'll be able to splice into the factory wires, but if it's factory wiring be aware that it may be brittle/corroded internally & not be accurate if operative at all.
The fuel gauge is one wire, and it's only ohms- or ground. I unfortunately don't know which wire to choose for you, but if you have a multi-meter you can probe all the wires and check them to ground. If your tank is half full it should be around 40-50 ohms.

Hope this helps...
