instrument cluster fuse location?

[HouseMouse]

Just had an RDS AUX tank installed on my 2026 3500. The Dash Board fuel guage stopped working. I have been under the truck looking for loose wires etc.and checked the fuse box under the hood. is there another fuse box for the dash location? Want to check the EZ stuff before I take it to the dealer. Thanks all.

Problem solved. Was draining my new AUX tank into the truck tank, Being that I didn't know where my level was at, I used my inspection camera down the truck fill tube. I interperted it as being full. After thinking about it awhile, what the heck. let's check. Went to the fueling station and added lots of fuel. Apparently, I read the reflection of the fuel level and not the actual fuel level. Just part of the learning curve.
