ISO: 2012 CIVIC EX NAVI w/o Premium Audio Wiring

[themoosestache]

I have a 2012 EX Navigation with out the Premium Package and am attempting to install an amp into the OEM head unit. I can't find a wiring table to save my life that doesnt show the Premium Audio information. I will be posting some photos of my 24p connector and the back of the Navi unit later if anyone wants to help me try and narrow down what each wire does. I appreciate all the help I can get.

Most have added a LOC to add amps/subs. One example in this thread.

I have a Line Output Converter, I'm just trying to get a definitive picture of what each wire leads to and the color coding so i can connect the LOC to the correct wire. Each diagram i find seems to point to either different colors or the associated wire port number is different. The only color that seems to cross over between the different diagrams is the ACC wire is purple. I'm heading out to tear open my unit and take some photos now.

Well I winged it a bit and just attached my remote wire to the purple one as that seems to be common as the ACC connection and attached my LOC to my rear left speaker just before it reaches the speaker connection. Seems to be working just fine and the polarity of the speaker connections colors line up with the premium stereo wire diagrams. I hope this helps anyone out there looking for info.
