Hi guys, hoping to get some help. Who's installed an aftermarket headunit into their CU2?

Tried to connect a pioneer f960dab using an aerpro stereo harness with the factory harness, but whilst the plug fits and the unit powers on, there's no sound.

I've had a look at acura tsx service manuals and the wiring colours and pin configurations seem to be different compared to our australian version, (our base cu2 models come with the 10 speaker premium sound system)

Any help would be appreciated!
