Installation with vehicle-specific harness CX-0xx
- Persistent current, Ground, ACC signal (Z) and lights signal (L) are pinned in the female ISO-connector of the CX-0xx. If supported by the CX-401 connect speed signal (S) and reverse gear signal (R) to the corresponding pins of the after-market device.
- Depending on equipment/vehicle the grey cable is occupied with the analogue phone mute signal. Connect to the corresponding pins of the after-market device.
- Connect vehicle’s female radio connector(s) to the corresponding male connector(s) of harness CX-0xx.
- Connect harness CX-0xx to CAN-Box CX-401 via 12pin Molex.
- Connect female ISO-connectors of harness CX-0xx to the ISO-connector of the after- market device.
Note for CX-035 (Ford): ACC and illumination are not digital but analogue signals on some vehicles. In this case connect ACC (Quadlock, chamber A, pin 16; pink wire) and illumination (Quadlock, chamber A, pin 13; orange wire) between female 12pin MicroFit connector and female ISO connectors, using the plugs of the harness.
