Aftermarket Headunit Wiring

[PhilW]

Just a quick one, ive got a Cencert non bose setup in my avant.

Is it the PC9-401 harness i need to connect up my headunit?

And also PC5-52 for the amplifief aerial?


Also im gettin some radio interference with my HID's, will this be the same when using the aftermarket headunit?

Thanks.
