Well I. Just realized the. Connector you pictured is the main harness side of the colum connector someone cut it in half or it burnt in half.... So
From the fuse 5 the orange wires go :
-The the colum connector , doubled up as u see In your pic .
- then it runs up to behind the radio where it turns into a multi tap female bayonet connector, this is where the dash lights,ashtray,shifter indicator in a console car , plug into .
So See if you have power at the doubled up orange in the pic you posted with lights on .
If no... U need to get a wire from bank 5 fuse to the orange wire that continues on to Behind the radio.
If yes ... move to the connector behind the radio and. Check for power.
If you find that the wire from the fuse block to the colum connector is bad I would run from the fuse to behind the radio and put the female bayonet connector on my new orange dimmed wire. Make sure u cut out or cap the old wiring to make it safe .
