Tried to install a new aftermarket stereo. Now all of my accessory power is out. Dome, gauges, digital odometer. Checked fuse. No problem there. Any ideas.
Check all connections in that area behing the stereo and in the column. I had a similar issue that was caused by a wire being slightly pulled out of it position and cause a ton of issue. All i did was use my push in tool and was good to go once the problem wire was found. Your problem does sound similar to my wiring issue.
