If the truck is not equipped with fuse 17, you will need to use CB022 - Actros jumper cable. CB022 should be connected between the SAM (fuse box) and the EIS/EZS. There are three cables on the required connector (one of which is for the EIS/EZS power supply), and CB022 should be connected to this exact plug. Then, connect the fuse relay (red cable) from the ZN151 set. CB022 provides a fuse for password extraction to be added. The first picture shows the connector, which is the upper left one.
