Hi!

I purchased a basic SONY CD in-dash stereo to finally replace my stock stereo.

I purchased the kit, antenna adapter, and the wiring harness for VW/Audi.

It was a decently straightforward process until I realized I only had sound coming out of the front speakers.

I think I need to connect RCA pins out of the back of the Sony unit to the YELLOW/GREEN/BLUE harness that comes out of the dashboard cavity.

Does this sound correct?

If so, do you know how I can get one of these wiring harnesses to fit the YELLOW/GREEN/BLUE harness?

Thanks,
Jon

Sorry, I forgot to mention I have a 1998 A4 1.8.
