Lh 2.4 two pin connectors

[Trevor57]

It seems that the two pin connectors for the knock sensor, coolant temp sensor, iac, and cold start injectors are the same. There is a black, blue, white, and grey connector. Does anyone know which connectors go with which sensor? I have the Bentley manual, and the wire colors do not seem to match up with my car, which is a 1990 240.

I'd get out the multimeter and check continuity between the connector back to the ECU connector to confirm the pinout and determine which connector goes where. Ideally probe from the back side of the connector to prevent accidental damage to the contacts.

For those interested in the future, the black connection is knock sensor, blue is cold start injector, grey is iac, white is ect.
