So the wiring came in yesterday. I'll probably install it next weekend, but I've been driving myself nutty trying to solidify the wiring required in my head. So I decided to lay out a diagram to make myself comfortable with it (see below). For those of you who have done this modification (pre-'16 models as well), does this seem about right? I'm 99% on everything from the steering wheel to the clockspring connector. From there to the stop/start connector I'm a bit unsure of my decoded layout.
I won't really know until I pull off the steering column trim, but this is what I believe needs to be done at this point. Of course I'll still need to wait on the replacement, replacement back cover to try everything out. I'm thinking that may take 3 weeks or so due to shipping from Japan.
