Oh, no, you are right. Sorry, I'm so used to everything center-dash related being completely different on the nav units. Might give it a try then. As ironmanco pointed out, it'd be nicer I think to keep the center-dash functionality untouched and use a button blank to the left of the steering wheel, but this is still an interesting option.

One thing that concerned me:

It seems to be like if we're relying on the resistance of the wire to control the current ("large wires will pop the fuse"), that's just asking for trouble/possible fire. The maximum current should be controlled by a resistor, or some other device in the loop, not the wire gauge. Did I miss here as well?

This one is similar to what Msportronics except that you have to DIY.

Her's what I think happened. Msportronics had to strip 54 wires, then pin crimp 54 microscopic pins. A total of 108 actions each. Lots of time involved. Artist / engineers doing repetitive jobs tend to quit sooner then stop producing. On the brighter side, these are same people that bring us innovations.

For some that want to make your own, here's the part number 25172-3NF0A. Someone sells a generic harness which you have to meticulously plug in up to 9 pins yourself. Probably around 2018 or 2019 is when you can't pay anyone to install it. You're on your own.

EDIT: Sept 2017: Here's an open source reference diagram, sourced from the service manual. Diagram shows wires going from switch to the VSP sound communication box. And switch Internal diagram. (2011-2017 LEAF). To be used only when at least one front wheel are raised off the ground (for troubleshooting purpose. Don't drive around with the sound off.)

16-pin connector = VSP sound communication box
8-pin connector = switch unit

The upper diagram is for a fixed illumination (which is easier to work with.) The bottom is for adjustable illumination and is a theory only since I haven't yet attempt to connect it. Some might prefer a 50mA fuse but I recommend two 820-Ohm resistors.

The most important wires are 11 to 4 and 11 to 8, ignition battery voltage lead. I'd make sure this wire is a thicker gauge than the rest. 18 gauge is good. Because it' should be strong enough to blow a fuse. This wire must have a secure connection to the VSP unit, Instead, I used two, no less than 820-Ohm resistor right at pin 11. I recommend it. Only problem is the indicator light is about 10% dimmer.

The thicker gauge is to protect the copper wire from burning other stuffs since they're good at popping fuses. Msportronics used tiny wires on his I believe could be unsafe. If they carry 12V, 1-20 Amps then a minimum of 18 gauge is preferred. I believe 18 gauge is common for automotive wires. You probably can use tiny wires if you put the correct resistor at the starting point (on the VSP control unit) exactly what you said at the end.

I have a 2018 model and interconnected a dash switch to the wire going to the speaker itself by reaching through the lower part of the front grill. It was not easy but it is effective in turning off the VPS sounds. However, turning the switch back on does not always result in an immediate return of VSP sounds. I think there must be some electronic sensor that turns off the systems if continuity through the speaker is not maintained. Cycling the car on and off has always restored VSP sounds. Hope this helps. I am still looking for a better way through pins 5 and 8 of the VSP box. Does anyone know if the pinouts changed in the 2017-18 transition?
