I have a 2023 uforce 1000, in the fuse box under the hood there is a fuse for backup along with a relay, the rear lights have an extra wire that isn't connected. I'm trying to figure out what I need to do to connect the reverse lights to get them working, it seems like everything is there besides the wire to the rear light for reverse, before I tear into it I was wondering if anyone has info on this as it seems maybe the wire could be there somewhere and the dealer didn't connect it?

Don't know about the 2023 UForce 1000, but on the 2023 ZForce Gen2 the factory wire harness has two connections, one for backup lights and one for turn signals. But the rear lights only has bulbs and wires for one.  So depending on which connection is made between the rear lights and the wire harness you get either backup lights or turn signals, but not both.  There are two models of the 2023 Zforce Gen2, one for the US that doesn't have the turn signals wired up but instead has the backup lights, and one for the rest of the world including Canada which is wired for turns signals but not backup lights.  If the same is true for the UForce and you have turn signals then it may not be possible to get backup lights without installing extra lights.

My u.s. model 2022 Zforce 800 also has fuse for backup light, but didn't notice an extra plug on the rear when I install turn signal lights. Admittedly I didn't look as I didn't realize the machine was wired for backup lights at the time  I decided to just wire some lights to a button on my Auxbeam control panel so I can use them for work lights in addition to backup lights.

I have a uforce 1000XL, I left the back up lights connected as set up by the factory, I tapped into the other but connectors to after market turn signals. Just had to find a ground wire to tie into to complete the turn signal install.
