IIRC that was not the final product.

Yes, the orange leather was a bit much...here is the final product, copper carbon fiber:

is this still the only way to do this conversion?

Anyone have any luck sourcing the M67 pigtail?

What about 3D printing one?

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

Yes, as far as I know. Once you have converted the HVAC controls you can do what ever you want to the center console. You can go extreme and make something like what scope22 did or just install the standard cubby and a 2din radio.

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 (

) 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.

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

Is this still necessary? I have a 2018 NAV NISMO, i want to down convert to a non-nav, do I need to buy that amp? if I"m adding a new head unit (and possibly amp) what does this do diffrently that the nav auto amp doesnt?

NoSlack13 · 10-05-2018, 12:12 AM

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.

if you're converting from nav to non-nav then yes you need a new AC box, you need one for base model/non nav and the model number you have is correct, you will also need AC controls for non-nav model.

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.

I have a sport model and I am looking to use an Arduino and custom code to control the AC from a center moutn tablet and delete the controls from my dash. Would it be possible for me to swap my ac auto amp out for a navigation ac amp and be good to go for canbus control? If yes is it this straightforward or will I need to mess with wiring.

VERY interested in this approach for many reasons.
