The "+" and "-" located in the panel to the left of steering wheel H091 (pins 4 and 12) send brightness adjustment signals to pins 13 and 16 of instrument panel E050. The reference earth arrives at pin 1 of H091.The Body computer M001 (pins 25 and 24 of connector A) is connected, via the CAN line, to the instrument panel (pins 6 and 5) from which it receives the "brightness adjustment" signal which is transmitted, via the CAN, to the radio P020 and to the climate control system control unit M070, where fitted. See E1050 CAN CONNECTION LINES The activation signal f3; pin 6 for versions with Cruise Control). See E2010 SIDE LIGHTS / NO. PLATE LIGHTS The side lights on power supply is sent by Body Computer M001, respectively:- from pin 18 of connector A, to the radio P020 preparation connector (pin A6 of connector A) and to the air conditioning/heater control lights G045.- from pin 52 of connector B, to the cigar lighter P070 (pin 1) and to the backlighting for the controls on the front courtesy light G010; See E2510 COURTESY LIGHTS The ignition-operated power supply line (INT), protected by fuse F49 inside the junction unit under the dashboard B002, provides lighting respectively for:- the switch control unit H090 (pin 14) from pin 12 of connector F of B002;- the radio controls for the clock spring D047 (pin 5), from pin 3 of connector E of B002;- the adjustable mirrors control H030 (pin 8), from pin 19 of connector C of B002;- the left control panel H091 (pin 2), from pin 4 of connector E of B002;- the electric windows control unit M190 (pin 17 of connector A) which, in turn, manages the lighting of the ideograms on the various controls on the doors, from pin 21 of connector C of B002. See E3050 ELECTRIC FRONT WINDOWS See E3051 ELECTRIC REAR WINDOWSThe Body Computer receives a power supply from the battery, via the line protected by fuse F1 located in the engine compartment junction unit B001. It also receives an ignition-controlled power supply (INT) from the ignition switch H001. The reference earth reaches pins 10 and 19 of connector A of M001.
