3. Installation
Switch off ignition and disconnect the vehicle’s battery! If according to factory rules
disconnecting the battery has to be avoided, it is usually sufficient to put the vehicle in
sleep-mode. In case the sleep-mode does not show success, disconnect the battery with a
resistor lead.
Place of installation is on rear of the head unit.
3.1. Interconnecting interface-Box, harness and factory head unit
Connect female 12pin Molex connector of harness RLC-POR03-2 to male 12pin Molex
connector of CAN-box RLC-M40-2.
Remove the female Quadlock connector of the vehicle harness from the rear of the
head unit and connect it to the male Quadlock connector of harness RLC-POR03-2.
