Solid Airbag Light and no radio

[Shades1]

Hello everyone!

I recently installed LED's into my dash of my 1995 300zx. During this process I DID turn the key to RUN when the controls (air control + lights) handles were unplugged.

After I finished and put everything back my airbag light is on (SOLID not blinking) and I have no power to my stereo.

I've checked the fuses and the THEFT relay - all are good.
I cannot attempt the airbag diagnostic mode due to the airbag light never blinks.
I know for sure the radio is correctly hooked up - has been working fine. And there is no fuse to the back of it so I can only swap radios later tomorrow to see if it's blown or something.
I have several aftermarket gauges on the same power as the radio - those are working just fine.

I've search the Internet forums for a long time now and can't find any solid solutions.
Thanks!!

Just an update;
I swapped radios with a different harness and that didn't work either.

I also noticed the dome and map lights don't work and the door chime/headlight alert chime doesn't work either.

Any help is appreciated! I'm banging my head against the wall!!
