OK - I had a bit of a *EUREKA* moment this evening while studying the pin diagrams and my wiring harnesseseseseses.
My mistake is I used the basic Metra 70-7552 wiring harness. It doesn't have anything in pins 6, 15 and 16 which are the very pins the steering wheel controls are coming through!!!
My plan is to replace my basic harness with the "ADVANCED" 70-7552 wiring harness (with the SWC wires I need to work with) and get it in after a whole lot of sniping. stripping and soldering.

Then looking at the AX-NIS32SWC-6V harness.... the 12 pin harness that goes into the ASWC-1 has the needed SWC pins grounded off together.

I will need to snip and splice into the wires of pin 5 & 11 of the AX-NIS32SWC-6V 12 pin harness and wire them into pins 6 & 16 of the "ADVANCED" 70-7552 respectively; while grounding pin 16 of the "ADVANCED" 70-7552 off.....

That **SHOULD** do the trick. I will report back if all goes well!
I may have made this similar mistake as well. Def interested in your results. Let us know.

I thought I’d post all of the parts that I used to install an aftermarket radio in my ‘13 Leaf. This works on the 13- 17 Leaf S. For the 16-17 Leaf S disregard the phone button retention harness as they have no BCM. Feel free to ask any questions.
Hi sorry long delayed question but did you make this work with the factory mic or did you wire in a new mic?

(& similarly did you disconnect the factory bluetooth module in the trunk?)

I'm coming late to this topic. I happened to notice in this schematic (edit: from this post) that the resistors seem to be swapped:


That voltage divider will reduce the amplitude by about 3%, which is negligible (0.1 dB). Are the resistors meant to be swapped, so that the amplitude is reduced to about 3%, i.e. some 15 dB?
GREAT catch coulomb! You are correct, the resistors are swapped. Please find attached the updated figure (I also updated the original post) - Sorry for the confusion

I just sold my 2016 Nissan Leaf S to Carvana and they wanted the stock radio instead of the Pioneer AVH-W4400NEX that I had installed in my Leaf. Not sure why anyone wouldn't like wireless Android Auto and wireless Apple carplay ...


Anyways, I now have an entire Pioneer to 2016/2017 Nissan Leaf S wire harness set left with the programmed ASWC-1 for SWCs, the backup camera voltage adapter, mic adapter, dash frame ... everything ready for plug and play for most recent Pioneer Stereos. Please, drop me a note if you are interested and like to skip the soldering and setup steps ... It is now just collecting dust at my home :(

I recently bought 2017 Leaf and would be interested in buying the pioneer unit and associated harness. Let me know how I can get in touch.
