I had my new cluster working then for some unknown reason I lost my assessory voltage feed. This pissed me off today sigh I will take a look in a while key in back position no voltage was working both ways. Checked my ground bam no voltage there fuse is good no idea why so far. Didn't feel like messing with hope nothing else happened and it's something simple. The blinkers worked the voltage showed up and temperature. Worked in both key positions on and assessory mode as it should. I'm sure since I lost my trigger it's not turning on now.
