Hi All

I'm trying to help my godson fit a secondhand Sony CDX-5090 radio/cd into his 2002 Fiat Punto. There is two
wiring connectors in the Fiat - one with what seems to be seven wires and one with four, and there is a
incompatible block socket in the back of the Sony plus two rca? sockets.

It seems that some form of adaptor is needed. I'd appreciate any advice about what we need to get it sorted out,
and any suggestions about where to get it.

TIA
Marc
