ECM Harness Connector Details

The following tables give input/output information for the two harness connectors used on the ECM.

Connector C0914 (black) - 52 pin Connector C0914 is used to provide inputs and outputs from and to the ECM for engine sensor operation.

Pin No.	Description	Input/Output
1	HO2S (pre-catalyst) heater drive	Output
2	Not used	-
3	HO2S (post catalyst) positive	Output
4	CKP sensor positive	Output
