My god the red color for that cubby is hideous. It looks like a cheap red box movie kiosk. Should have been black, not red.

Anyone have any luck sourcing the M67 pigtail?

What about 3D printing one?

Most of the parts needed you can get of off Ebay. Like the controls, lower bezel, AC Auto Amp, and the oem cubby. The only thing that is hard to find is the plug for the controller but Navster found a source. NH-025 (second one down)

is this still the only way to do this conversion?

Follow the link in the post above.
"10 Position .025” NH Connector"
That's what I used to make my own pigtail.

In your album you have a wire between the BCM and the A/C amp highlighted, the one for defogger coms. Is this in the harness already or is the wire omitted entirely for navi models and something that needs to be added to get the defogger working?

If you meant to have the pics show up in your write up, they don't.

A few suggestions:
Say which pin to which pin.
Maybe include a wire diagram. (Feel free to borrow mine out of my album)
Better description (or pic) of where the A/C Auto Amp needs to be installed/swapped out.
You talk about wiring in the illumination, say which pin(s) is the illumination on M67. (BTW I updated my M67 pinout pic in my album)


When I did my research I completely missed the fact that each system requires a different A/C Auto Amp. After looking again I realized my mistake. I confused the look up code with the part#. I hadn't looked up the illumination yet but, I knew it was a factor.

So, for those who want to know:
Non-NAV A/C Auto Amp part # 27760-1EA0A
NAV A/C Auto Amp part # 27760-1EA1A

I can't find mention of the ac temp amp Auto Amp part # 27760-1EA0A in anything related to the 2015+ (I have a 2018) do i need this part for this conversion in the 2018?

really appreciate the help.

Nice write-up, thanks for that :)

Bonus points for the longest disclaimer that I've ever read in a forum post.

Considering how many people I’ve helped correct their wiring the disclaimer was a good idea. Couple of them were stupid lucky they didn’t short something out. :icon14:

Got it! Thanks!



There is another option that I have been playing with, but it is still in its infancy. It involves using a microcontroller and some code to communicate on the CAN Bus. There is a very nice install that is demonstrated in this video which shows an Android app overlayed on the screen that provides the AC controls.

The above install requires an Arduino programmed to communicate to an MCP2515 CAN to SPI interface. The firmware project is here and the Android app project is here. Currently, the niscan project only works for the 370Z (:tup:) but can be modified to support other vehicles.

Going this route, you can keep the CAN based AC amp and use the above firmware project to mimic the CAN based AC controls. This eliminates a bunch of splicing and opens the options for custom mechanical controls. I believe that this will lead to much more flexibility in custom moves away from the stock Navi. My only concern is if playing with the CAN Bus and potential corrupting traffic needed to properly operate the vehicle. Perhaps this isn't something to be worried about. I am still wrapping my head around the technical details and going over the code.
