Wire tap for Voltmeter and USB

[Maverick1]

This is my wiring diagram that Cub Cadet provided me based on my model number. I'm thinking the best wire to tap is the RUN red/white on the key switch so the meter/usb hub turns on/off with the key. Is that the best wire to tap into shown here? thanks in advance.

Sorry if this doesn't open, I'm not sure how it's supposed to work.

What tractor are you working on?

Without knowing your tractor model or seeing the rest of the wire diagram I can't say for sure, but in general the "B" terminal on the key switch is the 12 volt input to the switch. In other words, the hot lead.
In your picture the "B" terminal wire is red/white so you don't want that.
Terminal "A1" (white wire) connects to "B" (12 volts) when the key is turned to Run 1, Run 2, or Start.

This is a model 13AOA9CS056 which is a cub cadet LT42" XT1 Enduro Series with Kohler 5400 series engine that I bought new in 2020.

I'll try to upload the full diagram, the bytes limit was exceeded.

Can 't make none of that out and can't find that drawing online.
So question, does your tractor have a carburetor or is it EFI?

Kohler says the 5400 series is a 2 barrel carburetor.

I'll also see if I can upload a better photo, it's clear on my end then when I post here it's blurry.

let me try this again using another hosting site. This one I can see clearly on the web.

OK got it.
The white wire coming off A1 of the key switch goes to your fuel solenoid through pin 3 of the engine connector.
The fuel solenoid, which is on the carburetor, is only energized when the key is on. So A1 is your guy.
You will have to open the wire harness and splice into the white wire at the plug on the back of the key switch.

The plug at the key switch is behind the gas tank and difficult to access, though I'm sure that's common. Can I tap into the white wire along the loom where I can access it better? There's plenty of easy access to the white wire before the loom gets to the Kohler engine. Thank you so much for all your help!
