Troubleshooting your fuel level sender

So today I followed the wiring back to cluster.
Turns out the two senders share the black/ brown trace and send the other two wires along with a single merged black/yellow-ish trace back to cluster.
So a total of 3wires go directly to cluste from the two senders.
I pulled the two plugs from a spare loom and twisted the unshared two wires (one from each sender) ( blue/red trace and white /green trace) together.
Filled the tank and measured impedience basically as parallel from both senders and got 9ohms which I believe what is stated in the SM.
ILL test at all the gauge increments to see if it seems consistent and post results.
I don't think the ecu is making any calculations what so ever as the car I traced these wires to cluster had no ecu attached.
