92 Accord dash wiring problem

OK so I'm on my way to work this morning and my Radio,dash lights,heater controls, blower all quit at the same time. My gauges still work, clock works, Rear def, and hazards work, While checking what did and didn't quit I discovered that my sunroof had also quit. There are no blown fuses and the systems seem unrelated. Does anyone know if these sytems share a ground and where it might be located, or any other ideas.

Thanks
Greg

OK so far it looks like I am looking for grounds G401 and G402 But the online copy of the manual dosn't include page 16-20 to see where they are located can anyone help with this part

Haha I have the same issue sort of. I have an 88 Accord. The lights for the AC/heater/dash lights and the digital clock are out.

RANDOMLY they will come back on and work.

Also when I took my steering column apart to check the ignition switch and put it back together. Apparently I moved some wires to the point where they are getting a bad electric signal because now my turn signals blink double speed. Sometimes while the wheel is turned sideways it wont happen but for the most part it happens. Not a big issue but it annoys me.

I love Honda's but over the years Ive discovered. They make up for their durable engines with shitty electronics and wiring. Tell me how it goes when you get it fixed. Thanks.
