Wiring diagram for steering wheel heater?

Greetings, fellow Leaflings:
I am working on a mod for my steering wheel heater on my 2015 SV. I picked up a "motor controller" on eBay, and want to wire it in to control how much power is delivered to the steering wheel. I started this project ages ago, and I have a memory of seeing a wiring diagram that included the steering wheel heater and its switch, but now can't find it. I've searched and searched through the manuals at https://www.nicoclub.com/nissan-service-manuals, but can't find any mention of the steering wheel heater in anything I find there.

Can anyone please direct me to a wiring diagram that shows these components?

Thanks

Thank you! Somehow I managed to not find that, even though I think I went through that manual.

Oof, even with that diagram, I can't locate the wire I want under the dash. A day of messing around, and I've gotten several panels loose so that I have access under there, but all the wires are in there so tight, and bundled up in black tape. I'll keep working on it . . .

Hello. Very curious as to how this went. Why a motor controller, and not simply a potentiometer or power varistor or something similar?

Did you get it working?
