^^ That would be correct^^ Here are how dimmer controlled dash lamps work:

The park/ tail light circuit must be working. The headlight switch must be in "park or "head" and the dimmer control twisted some to the left. This results in power going through the dash dimmer control and out on the TAN wire where it goes down to the INST fuse. From the INST fuse, dash lamp power is branched off on orange wires

So BOTH the tail and the INST fuses must be good for the dash lamps to operate.

Makes total sense, thank you. Would I be able to ask one more thing from you? I'm having little luck figuring out why I keep blowing the tail light fuse and to the best of my current ability everything seems to be matching up with the diagram for my harness aside from one thing. I ran out of light today and tomorrow will be pulling back the electrical tape to confirm but I think I may not be connected correctly at the point highlighted below. aside from possibly not being grounded I'm trying to reason where I could be shorting out and have inspected the wiring from the fuse box all the way back to the tail lights and aside from a tiny tear in a light blue and brown wire behind my kick panel everything else has been corrected or is in good shape. Any suggestion if I'm missing something or just going about this all wrong?
