Hi, I just recently installed a new pcm in my 04 Wj special edition. When starting the jeep, all gauges flip to the right and stay there, and the tachometer n speedometer don’t move at all, even when driving. Also my radio does not work. Is this most likely a bad fuse, bad ground, or something I’m overlooking. Side note, I did change the back plates of the instrument panel from black to the white ones. Not sure if this may have anything to do with it. Thank you
