I hadn't realized that you responded to my comment/post yet. I apologize for the late reply, and want to thank you for your response.

I have made it a point to look for you and IBallEngineer when searching this forum, as you two seem to really lay things out and know what you're talking about. Since my comment a few days ago, I've narrowed the pin on 3C to terminal 7- blue with yellow. Since snipping that wire, no more blown dome fuse. I've been looking at the EWDs and have yet to figure out what that wire controls.I see you stated in your response that it controls the rear dome light.

I actually started going down the list of everything you mentioned in another post about what is on the dome circuit, unplugged everything mentioned including the rear dome and powered it off, still had the same problem. Clipping the L-Y wire on plug 3C terminal 7 seems to have "fixed" the fuse blowing, but hasn't helped with rectifying the cause lol.

I'm actually in the process of using a thread you and IBallengineer are on regarding 2000 4runners and the lovely DRL nightmare. I bought this 4runner earlier this month (have always wanted one) and it had a few issues. I was wondering why the headlights left a lot to be desired and have figured out why...they're stuck on DRL. I am down to seeing if it's something to do with the combo meter now, tried all the other troubleshooting y'all had mentioned. I plan on going out shortly and checking.

I love that this forum has helped me with repairs and chasing electrical gremlins!! I will say, there's nothing worse than seeing a request for help, someone writing out a very detailed reply of troubleshooting tips, then the original post ghosts with no results. I will be sure to NOT be "that gal".

Thanks again 😍

P.S. I always put a meter on fuses to check for continuity, never rely on how they look when pulled from the fuse panel. 😂
