4 EMC Recommendations
 Do not route the sensitive signals in parallel to high tension wires (ignition, Digital I/O).
 Wire from CCU to Vehicle battery should be as short as possible.
 Avoid loops in the routing.
 CCU ground shall be as short as possible fixed to chassis or directly to battery ground
 For CAN wiring, it is recommended to use a twisted pair (Figure 3).
