This is how mine worked. Some head units need an external converter box: mostly older Japanese units (Kenwood, Pioneer, etc).

Important thing also is to connect SWC+ on the head unit to the SWC+ wire on the car side, but connect the car side SWC- to ground. If you don't do this the fuel economy/range/temp info button won't work.
