‘66 Barracuda Fuel Gauge Pegged!

“Disconnect the sender wire at the sender and the instrument cluster. Set you meter to ohms and check the wire to ground. If it reads continuity, that wire is shorted.“
I’m not showing continuity, so rear harness is good.

“You can separate a harness connector behind the left kick panel and test sections of the dark blue sender wire. If the wire is good from that connector to the sender the ohms measurement would be relative to what level of fuel in the tank.“
It is, Redfish, showing 16.5 ohms, that is at the kick panel with the plug disconnected.

But, when I put a probe into the mating connector, the one that goes up into the dash, I get a continuity reading of 35 ohms (battery is disconnected).
This tells me there’s a short in the upper harness, correct?
