Has anyone done a SWI-X in an FX35?

Hey guys, thanks for reading this

Here's the scenario:

I have a 2005 Infiniti FX35, I'm customizing a Pioneer AVH-P6800DVD into the factory LCD area. Everything's done and working BUT I wanted to add the PAC Audio SWI-X Module.

I found info on the  PAC site
https://www.pac-audio.com/swixprogramming/showstepbystep.asp?RadioGroupPioneer=0&InterfaceChecked=1&mmSearch=Infiniti&Submit2=Search+Vehicles&ID=316

But I can't seem to find the maxima16b plug. I called PAC and they just told me stuff I already knew and couldn't find.

Can anyone verify that is it in fact the 16b plug as stated by PAC? And maybe tell me the location of this mystery plug? Or if PAC is wrong aboutt he plug, possibly tell me which plug I need to tap out from?

Thanks in advance!

here's the project in the works
