Autometer Fuel Gauge

Hi y'all. In the process of swapping out stock gauges in the Mustang and replacing them with Autometers. Wondering if anyone knows the color wire that comes off the fuel level sending unit that needs to be connected to the new gauge, or can I just wire the new gauge to the wire (yellow/white stripe) that is in the gauge cluster harness?
Thanks!

Yea, I think I'll hook into the yellow/white in the harness, seems like that should be it.
