Instrument Cluster Dark After Bumper Install

[4runnerguy]

I had a new rear bumper fitted, and I noticed my clock had reset. I assumed the installer disconnected the battery before working on the electrical and didn't think any more about it. However, I took the truck for my first night drive and the instrument cluster wouldn't light up when the headlights were on. The turn signal indicators light up, the e-brake indicator lights up, etc., but I don't have the "backlight." Anyone know what I might troubleshoot to diagnose the issue?

Thanks!

Make sure the didn’t adjust the dimmer all the way down. Turn the little knob left of the steering wheel.

As far as i can tell from my manual, it should be here... I'm not seeing it.

Short of that, any other ideas?

In case anyone experiences this, I dug into the issue and the brake lights weren't working either. It turns out the "backlight" and the brake lights are on the same circuit. The connector for the rear bumper wasn't properly connected and a fuse was weirdly bridged. New fuse and fixing the connection resolved the issue.
