Remote start ignition switched circuit?

[silverheep]

I’m trying to find a circuit in the underhood power distribution box that is ignition switched and is hot when remote start is activated.

I’ve installed a Switch-Pros unit, and I’d like it to receive an ignition signal both when the truck has been remote started and when the ignition is actually on, as I’d like to be able to have it turn on my heated windshield wipers when I remote start the truck.

This is on a 2024 2500 Powerwagon (Level 2). So far, I’ve tried both the ignition side of the dash power fuse (F90/91), and the fuse for the back seat usb ports, and I figured before I keep on stabbing blindly, I’d see if there’s one I’m not thinking of!

The ignition run circuits are not active when the truck is remote started, since the ignition switch is not actually in ACC or Run position.

Fuel lift pump circuit?

Fuel lift pump circuit?

I’ll check, that’s a good thought. Otherwise it seems I get to make a harness to trigger with marker lamps if the ignition circuit is not on.

@H3LZSN1P3R loosely based on your idea, I figured anything required for the engine running should work, ended up using a fuse tap at the F63 coil fuse, and it’s working like I’d hoped - on with both ignition and remote start.

Edited to add - does not come on in the accessory position, but for my use case, that isn’t a problem.
