Default Wells TPS 4185 Issues

Hi guys,

I purchased the Wells TPS 4185 and made a bracket to mount it to my throttle body. The consensus seemed to be that the ground could be on either pin 2 or 1. I repinned the connector per the attached image from the thread (in the connector, not inside the TPS) and I am still not getting any value in tuner studio. I report a value of 0. See the way that I have repinned the connector in the second picture. Any ideas why I am not getting any any data? Did I miss my morning coffee and pin the TPS connector incorrectly? Did a mouse chew thru a wire?

I've been doing some digging and have answered my own question. See image below straight from wells.

I will swap the signal and ground and that should fix my issue.
