I bought an aftermarket stereo and dash kit and being a complete idiot, I didn't order any harness or radio adapter. After figure out that I am in fact an idiot, I don't trust myself on ordering the correct harness the first time. Could someone pointed me toward the correct radio harness and antenna adapter for my base model 2008 Honda fit ??


P.s: being station in Germany is awesome except for waiting a month on everything that you order online.

 

The antenna adapter is this one:



Should be about $10.

Second one depends on which aftermarket unit you have. Some use ISO connectors on the unit. Others require some wiring because they use their own connectors, to get from Honda to that unit without ISO connectors. Some may be able to pass Honda > ISO and then ISO > unit via plugs. But expect to have to do a bit of twisting.

I'm not sure exactly what's back there yet in terms of wiring, because I'm doing mine next week and I haven't bothered looking yet.
