You may even have to turn the Key to ACC or On to get power also in that truck?

Check the fuse in the Fuse panel, and make sure the fuse behind the HU is good if it has one. Id start there. If all good. Id pull the HU out and try powering it up at the Battery. You could possibly have gotten the wrong wiring harness??? It happens

What’s the bare minimum as far as wires needed to be connected to bench test the HU? 12v constant, 12v ACC, and ground? I have a 12VDC power supply in the shop I can bench test it on, since it’s like 12* outside right now =)
Thanks for the advice

Well bench testing the HU comes alive. Good to know. Wonder what I could have borked. Thanks guys!

Embarrassing as it is, the firmware didn’t take on the first Maestro flash so it wasn’t passing accessory power through. Works now!!

Nothing to be embarrassed about man. All these new electronics are so much different from back in the day when I first started with this hobby.(Like 1984) Tells you about how old I am, LOL, I always run across an issue with new products. My old amps and HUs are very simplistic. I always use a 12v battery and/or a 200 amp charger while testing things out.
