Some assistance with stereo wiring.

I’ve got a 2010 CSX. So I’ve purchased an aftermarket head unit (JVC KWV940BW) along with a harness to retain the factory AMP. Now I’m not getting any audio, I’m guessing because the amp isn’t getting any power. All the digging I’ve done points to the audio connector, Pin 20 light blue… but all the documentation is for the 8th gen civic and my connector does not match the wiring diagrams for the 2010 Civic SI. I’m at my wit’s end. Anyone have any experience with these? I’ll attach what my OE harness looks like. I’ve tried some of the blue wires already. At this point I’m just taking shots in the dark.

I think starting from the 2010 model the Audio sys with Nav pinout has changed. They no longer have the individual port for back-up camera, like they used to in the 2006-08 model.

Here you go, hope this helps you with your upgrade 😀

2009-11 Audio Sys with Nav

Thank you! I’ll have a look at this when I have a few days off. I had a look in the back and I don’t have a subwoofer. My CSX doesn’t have a backup camera either—why would there be pins for those in the iTech? So I do have an amp then. I see that the tweeters and front speakers run off of the same pins, how is the HU able to differentiate between the two? Are the speakers two way or three way?

this is more complicated than I thought
