total is recommended The splice should be as close to the ECU as possible All power supply lines must insure disconnects do not occur for longer than 400us Note 2DC resistance between battery and ECU should be minimised to avoid volt drops at a peak current of approximately 20Amps A value of 40mOhms total is recommended LOCAL Ground connection should be made within 200mm of ECU to conform with CISPR 25 recommendations The splice should be made as close to the ECU as possible Minimum wire thickness is to be 8AWG Note 3Combustion noise sensor connections should be made with screened wire Total capacitance not exceeding 450pF Under no circumstances should the screen be connected to chassis The screen should be continuous and in line connectors avoided The screen should start and finish as close as possible i e 50mm Vehicle variations should be minimised For screen definition see EMC Recommendation Table Note 4CPS wires should be twisted together throughout their length A minimum of 33 twists per metre Twist should start and finish as close to connectors as possible i e 50mm For twisted definition see EMC Recommendation Table Note 5All RPS wires should be twisted together throughout their length A minimum of 33 twists per metre Twist should start and finish as close to connectors as possible i e 50mm Harness length should less than 2 metres For twisted definition see EMC Recommendation Table All RPS wires must insure disconnects do not occur for longer than 40 us Note 6Injector wires should be twisted together throughout their length A minimum of 33 twists per metre Twist should start and finish as close to connectors as possible i e 50mm Total DC resistance should be between 100 and 200mOhms at 20OC All injector pairs should be within 15mOhms of each other For twisted definition see EMC Recommendation Table Note10Where fitted SCP wires should be twisted together throughout their length A minimum of 33 twists per metre Twist should start and finish as close to connectors as possible i e 50mm For twisted definition see EMC Recommendation Table Note 11Where fitted CAN wires should be twisted together throughout their length A minimum of 33 twists per metre Twist should start and finish as close to connectors as possible i e 50mm This feature is only required for development For twisted definition see EMC Recommendation Table Note 14The positive feed to higher current inductive loads where applicable IMV SOST and EGR should ideally be separately connected to the battery in order to avoid inductive load currents in the ECU supply connection These wires should be as short as possible See Diagram 1 Below Note 16CID wires must insure disconnects do not occur for longer than 10 us u u 7 1 F 7 E 6 1 E 8 F F F F 1 F 1 5 7 8 F 1 E F 1 7 5 7 u z

foil tape spirally wrapped and lapped 50 minimum exposure at the connectors The shield terminates to the associated module s power return within 300 mm of the module s power return pin The drain wire shall be equal to or greater than 18 AWG Screen should be continuous through out its length In line connectors should be avoided Shield should terminate no further than 50mm from the connector Twisted Wires Minimum twist rate of 30 twists per 1m One twist is 180 degree rotation Twists should be continuous through out its length and should terminate no more than 50 mm from connector Twisted wires shall be terminated in adjacent terminals located away from power and return connections Starter Motor Battery Feed Wires The starter motor wire shall be routed at least 250 mm from all variable
