You're the man! Thank you!

A few questions. I have the basic concept of how to do this but of course I run into a few glitches. My setup is as follows: 2012 Honda Civic LX (no nav, no phone) in the factory model radio, but I do have steering wheel controls for volume, source, and channel selector. I am installing a Pioneer AVH-5800 that was already installed in my truck (which I did myself / no issues). The Civic's factory harness has 3 plugs - 24 pin, 20 pin, & 14 pin. When you enter the required information into PAC's website it shows the 24 pin, the 20 pin, but then a 32 pin. So, this is where I get confused. One, where is the 32 pin at in my Civic? Second, if you were to look at the wiring diagram that I am to go by, the 20 pin shows Pink Data 1 to Blue 3, but the pin diagram show pins 3 & 13 - so why 2 pins but only 1 set of wire colors? Lastly, the Control Pro Wire Color - Function to the Radio shows Red/White - ACC Out to Accessory Unit, then SWC Output to Radio. The PAC SWI-CP2 that I purchased does not have a Red/White on the harness w/ the aux jack plug (not sure the correct name for that plug), but the smaller harness has the plug and then a blue, brown, and black wire. I do see the installation note where it states C3 can be found at the Hands Free Link Unit which is located behind the glove box. Is this the 32 pin plug by chance? TYIA for any help you can provide.

This thing doesn't work and steering wheel controls aren't important.

I have the maestra sw. not sure how i use the sw control 1 and 2 from the stereo. The maestra has a light blue line along with a make aux cord. Then the separate wires that connect to the car wires.
