08 fuel gauge replacement issues

Had the needle dancing crap. Replaced the parts in the tank first and filters. Still dancing.
ordered a new gauge and when I plug the new one in it doesn't work.
Is there some magic to marry the gauge to the bike? It just stays dead on empty.
I plugged the old one back in and it still dances.
I'm thinking I got a bad gauge from the dealer.

Reply for clarification

My main question is, The most likely for this behavior would be that the new gauge is bad correct?

Check the pins in the gauge connector plug....

On a softail I had, after removing the gauge, I had all sorts of issues with improper or intermittent gauge readings. I know it's a different gauge set up, but I believe it has a similar connector plug into the harness, if I remember correctly. One of the gauge connector plug pins got bent as I was plugging in the gauge... The gauge didn't work well for awhile...

I finally inspected that plug-in connector, found the bent pin, re-pinned the connector, and all is well...

Just a thought about something to check...

Original part number 75111-08
Part number on box for new gauge 75111-08
sticker on new gauge that reads empty all the time 75111-96C
sticker on new gauge says 80-14 Ohm
Sticker on OEM gauge says 252-40 Ohm
