Fuel Guage reading

[geostang351]

I have installed a new after market fuel gauge into my cluster and have a question concerning the sensor for determining the amount of fuel in the tank. Ford gauges call for a reading of 75 ohms of resistence when empty and about 13 ohms when full. Do I hook up the multimeter (+) to the sensor wire and the (-) terminal to ground to find this reading? I assume yes as I got a reading of 85 ohms and the tank is basically bone dry doing it this way.

Thanks:SNSign:

Sounds right to me.
