Just got a 2019 Sport Sedan MT and am trying to install a DSP and 5-channel amp. I chose the AX-DSP because it's decently priced and is mated to the only aftermarket harness for our headunits. I have the 7" headunit without an OEM amplifier.

Comparing the harness to the wiring diagrams from Honda showed a match so I didn't expect there to be any issues. It *should* be plug and play but the DSP does not seem to be powering on. My only theory is that there was a change between 2018 and 2019 in which pin A23 "ACC: Power source for accessories" (see https://www.civicx.com/threads/headunit-wire-diagram.2886/#post-45909) is now listed as A23 "RR CAMERA ACC DIODE: Power source for accessories or detects reverse signal". Can anyone tell me what that means? This behavior would make sense if there was no signal to ACC. Should I run a new ACC from the fuse box and splice it in to the DSP?
If anyone has any experience with this DSP, any advice would be appreciated. Metra tech was completely unhelpful and dismissive so I'm seriously considering just returning the thing and getting a Rockford Fosgate DSR1.
