Any progress on this, running into the same issue?

I just tapped one of the fuses in the driver's footwell fuse box. I forgot which one but I can take a look tomorrow

Are there any ignition only fuses to tap into in the under hood fuse box?

I started mapping the cabin fuse box, diagrams attached if this would help anyone else with a 2020+. Looking for a fuse to plug into for my switch pros 9100, plugging into the only open fuse slot is power not tied to the ignition.

Any help would be appreciated.

Switch Pros 8 button controller (uses the blue wire for power) to an Add'a'fuse

Option #1 KDSS, because I don't have KDSS even though I have a fuse for it.

Option #2 IGN No 2 or 3?

Switch Pros automatic dimmer control (White Wire)
Use an Add'a'fuse to the TAIL fuse

thoughts?

Not from any of the install videos I have watched, but most of them skip this step or are installing on an 2018 or older. I will start checking my service manual tonight, good thought.

First glance I think the only candidate would be 10A STOP fuse, but I think there are systems utilizing this fuse that are not tied to the ignition.

For 2020+ for ACC switched power, I've used:

Under hood fuse box: INJ, and I'm 90% sure DEICER will also work
Driver footwell fuse box: Empty slot first column six up from the bottom, ACC, S/HTR FR, COOLING

All those fuses have worked for me for ACC power. I'm not really worried about power draw because everything I've added via fuse tap has a separate power lead for power, it just uses the ACC power via the fuse tap to tell it that it's allowed to turn on. That and I try to pick low amperage fuses of things I almost never use, like the power seats mechanism, or the seat heater circuit, or the power outlets. I absolutely will not tap a fuse that relates to the drivetrain or anything critical to vehicle operation.

Worked like a charm, thanks for the help!
