wiring harness on sl-600, ea motors
The wiring harness on the sl-600's and s-600's definitely are faulty. The insullation crumbles to dust. When the harness moves then wires touch and thigns in th eelectronics go crazy. the electric throttle actuators each have wiring harness attached to them that also fail.
Bosch made lots of bad wiring harnesses with 'bio-degradeable' insullation
