Accelerator Pedal Position Sensor Connector

5.5.1 ECM Connector Endbell

An AMP 638092-1 (Caterpillar part number 126-1774) Connector Endbell is available to provide additional protection and controlled wire routing for the harness at the ECM.

5.5.2 Twisted Pair Wiring

Twisted pair wiring must be used for the SAE J1587 Data Link, SAE J1922 Data Link, and the vehicle speed signal wires. There should be a minimum of one twist per inch within the harness. All twisted pair wires should not be twisted within an inch of the connector to avoid seal stress. The speedometer and tachometer outputs should also use twisted pair wiring. SAEJ1939 Data Link wiring should comply with SAE J1939/11 specifications.
