Where is this wire supposed to go?

OK guys I found this wire under the dash next to the speedo where all the wires branch off the main harness. Orange. I have a 77. See photo.

one of the gas tank senders. if you have dual tanks then it goes to the one of the tanks and you prolly arent getting a reading from that tank. if you have a single tank then it goes to the aux tank that isnt there and is not an issue

Yes only 1 tank so that answers it! Thanks again! You guys on here are amazing!

The 2nd tank wire would be at the tank switch - not at the instrument cluster. And it's Y/Wh; not Or. Your pic shows the gauge wire, which needs to be connected to SOMETHING for the gauge to work. Look at the Right side of this diagram:
