New Head Unit

[Howard]

I have a '96 Cinquecento SX.
Will I need a wiring adaptor to allow me to install a new head unit, for example a Pioneer DEH-P3630MP?

The current radio is some Fiat/Philips cassette thing.
Without the two removal clips (Gonna have to get my dad to bring some home from his work) I can't look and see what wiring harness/connectors I've got.

Anyone suggest what I'll need to buy, if anything?

When I put my JVC headunit into my Cinq S, I found I needed the wiring harness supplied with the headunit. All I had to do was attach the right in car wires with the right harness wires by using bullet connectors.
Hope this helps.
