Reverse OEM radio harness?
I've seen on eBay reverse radio harnesses that plug into the back of the factory radio. Has anyone seen one that would work on a 2012/2013 radio?
Background: I'm installing an amp on a factory 2013 system along with new speakers. I'm trying to avoid running new speaker wire and trying to avoid cutting my factory wiring harness. I realize I could just use t taps to get the signal from the radio into the loc, but the problem will be feeding it back into the speakers without having to either run new wire or cut something. If I could find the OEM speaker wiring harness, I could just create my own radio-to-loc-to-amp wiring harness and then tap into the original speaker harness from the amp.
