you can do it!
I haven't had the chance to do anything with this because I've been too busy. The shop at work will be able to help me add the additional wiring to the connectors.supercrz,
Where you able to figure out the wiring? If not, I'll be glad to help.
FWIW, the pic of the connector w/ blue background in your 1st post is from my 09 Civic.
Is this the same pin configuration for the wire harness on the right? It is also 24 pin.Audio unit connector A, 24 pin (built in stereo amplifier type) Page 23-30:
A1 black ground for audio (G503)
A2 white detects illumination control signal
A3 pink b+ power supply
A5 grey left rear speaker signal+
A6 brown left rear speaker -
A9 blue right rear speaker output +
A10 orange right rear speaker -
A11 white ground for audio remote switch
A12 green security signal from MICU
A13 blue detects scan tool signal (serial data)
A15 lt blue output driver door speaker and left tweeter +
A16 grey driver door speaker and left tweeter-
A19 blue output passenger door and right tweeter +
A20 red output passenger door and right tweeter-
A22 pink detects voltage for audio remote switch
A23 blue inputs vehicle speed pulse from ECM/PCM
A24 purple power source for accessories
Page 23-42 to 23-44 on the manual show that the navi needs the external amp as the audio lines are all preamp level. This in itself isn't an issue as the cable for the amp is 100% reliant on the radio for everything from power to audio so it makes it simpler to add.
Adding connector "C" were you ever able to get the radio to power on? There's a ground on this too, so it would be prudent to connect this as well.
I have not had the chance to work on this, due to work and no time to do further research on this. I still need to get the unit to power up.Any news ?
