Need ACC or Ignition signal

[SeaSickSailor]

I need to find a fuse in my 2019 Power Wagon that has a signal on it when truck ignition is on either ACC or RUN. It’s for operation of my Switch-Pros system. I can’t use fuse 90/91 as that is in the battery position to enable my solar charger to charge my aux battery. Either a fuse that I can fuse-tap or a convenient wire that I can tap. Any ideas? Thanks.

Blower motor resistor plug?

Uhhh, I don’t even know what blower motor you are talking about. Sorry, I guess I need more smarts on these engines and supporting systems. Can you please shed a bit more light on this? Thanks.

Have sent a harness to a member for testing. It's being sent back for some refining. Things are in the works hopefully I can get it figured out and into production.

I do know that FCA changed some of the maps on the operation of the 48-11 to "improve" it... LOL... But with my new shoes (Falken ATW3s), hopefully be all good, even though I restrict my 4 X 4 to things like getting hay and trailer hossies. Thanks for the effort and stuff U do to help folks, especially the PPL with the 44-44 systems, which I had on MY 2015.

Are you sure that we are talking about the same truck? Mine doesn’t look anything like what that video does. No blower to be found anywhere nor connectors as shown.

Ah crap didn't realize it was a 2019. Sorry man, do you have the full center concole? Could probly tap power from the back of the aux jack in the back if you do and it's hooked to key on.

That’s the jack I want to use on battery so no go there. And yes, I do have the full central stack with 12” screen.

So, no ideas floating around in here about where I can tap into an ACC or ignition signal on a 5th gen power wagon (other than fuse 90/91)? I believe I posted this query in the 5th gen audio and electronics forum. Please correct me if I’m wrong. Thanks.

Ok. So no help on what fuse to tap. How about a wire or connector block somewhere that I can tap. I know someone out there has come upon this problem before. Thanks.

not for sure but f66 its rather easy to find using multimeter and then use a fuse piggy back

Don’t think that will do it. The bottom block of the attached pic lists what f66 (10amp) fuse is for. Maybe I’m wrong.

Where is your switch bank going to be? If it's on the roof like some I know you can easily tap power off the mirrior like I've done to power my radar detector.

Thanks. I’ll check it out.

The mirror wires you'll want are pink with yellow line for acc power and black for ground.

Eureka! That works great. Thanks so much.

Your truck should have come with a plastic bag with a bunch of wires in it for upfitter switches. In that bag there is a plug with wires coming off of it, purple/yellow a looped wire pink/white and looped wire red. The pink/white is powered ignition on maybe also acc on.

Forgot to mention that the plug I am referring to plugs in up by e brake foot pedal. Sort of up and behind it.
