No power, but can't find blown fuse

The saga continues. Had some glitches with the AVH 4200NEX (voice command would not work intermittently and volumes started cutting in and out). Crutchfield swapped it out for me (GREAT CUSTOMER SERVICE AND TECH SUPPORT!!!!)

Installed the new one, then the steering wheel controls wouldn't work. Pulled the Maestro and reflashed the firmware; still dead. Pulled the units out to double check connections and then nothing. Found a blown IGN fuse, still no switched power to the connector Maestro pulls from (different from the source the OEM HU uses).

The Audio headphone jack from the Maestro to the Pioneer had 2 wires broken at the connector. My guess is these blew the fuse (I'll verify with Maestro)

Picture of the factory HU and connector. Does anyone have the pinouts for this connector, specifically the 12V switched? It's second from the top, right next to the constant 12V in the corner.

 

anyone?

 

anyone?

 

These are for a 2012 X-Runner. If they don't help or are too small, let me know and I'll email larger ones. hth
