Fusion / Fiesta 4500 radio · 2S61-18C815-AF / 4S61-18C815-AA

The C344 table is based on Ford’s 2002.25 Fiesta non-navigation factory diagrams (415-01-00 and 415-03-00). The table includes all four speaker channels. Wire colours are listed at the radio where documented.

Fiesta JH1/JD3, pre-facelift: Applies to vehicles fitted with the Visteon 4500 and the rectangular 24-way socket. Ford’s 2002.25 diagrams document the cavity assignments below.
European Fusion JU2, June 2002 to October 2005: Adapter documentation matches the Visteon 4500 and 24-way socket and independently confirms cavities 1 (battery), 13 (ground), 18 (analogue remote signal) and 19 (remote ground). The remaining Fusion circuits, including speaker wire colours, require confirmation against its own wiring diagram.
Later Fiesta and European Fusion: If fitted with a 5000C, 6000CD or 6006CD and a 40-way Quadlock connector, use the Quadlock pinout. Both connector families appear in 2005 application listings. Match the radio label and socket on the vehicle.
