WCCC-Electronic Low Fuel Indicator Question

My 69 is in the shop having some electrical work done. I purchased one of these from WCCC. http://www2.cougarpartscatalog.com/elfi.html
After installing it and now going to through the test procedure, the low fuel light is ON at all times, including when the key is turned off.
Any help is appreciated.

Sounds like the prove out lead is on the wrong side of the solenoid?

Bingo.

It goes on the starter side

Thank you all for the responses.

Turns out that wasn’t it. It looks like maybe there’s a bad part.

Thanks again,

John
