This is in my 2007 Saab 9-7x 5.3i. I used a fuse tap on fuse #48 IGN 0 10a under the rear seat for switched power for my aftermarket radio. The Crux adapter I'm using would turn the radio off randomly and Crutchfield recommended connecting the radio to a switched power source. After connecting the wire, I drove the car for a few minutes and everything seemed to be working. Then when I parked it and tried to turn off the key, the key was stuck in the ignition. It wouldn't let me turn the key from ACC to OFF.
I took the tap out and put the fuse back in and was able to remove the key. I tried reinstalling the tap with 2 10a fuses instead of 1 this time and the oil, coolant, and gas gauges read zero, the gauge light was on in the cluster, and stabilitrak is off. I checked the instrument cluster fuse under the hood and it was fine.
I unplugged the battery and plugged it back in after about 15-20 minutes and that fixed everything.
What I'd like to know is: what fuse or circuit or module do these gauges and stabilitrak share? Why did tapping/removing the IGN 0 fuse cause all this?
