2004 Crown Vic - PCM - Wiring/Pin Connector Diagram
 
Hello,

Would anyone have a "2004 Crown Vic - PCM - Wiring/Pin Connector Diagram" ... have a open circuit with alternator; however, need to know location of the pin in the PCM connector to test for continuity.

Thank you in advance.

Hello

No code.. issue is i have a open wire from alternator to PCM and to test and replace the wire, I need the diagram of the PCM plug to determine location of the pin and the pin number to test with a continuity gauge.. then if open.. rewire

Thank you in advance

Hello,

Tested and not open circuit and have replaced the PCM (for another reason... i.e. new keys) and still have dash light on..

Alternator output is stable and good (recently new .. replaced due to low voltage)

New battery cables (both) and good grounds.

Would anyone have any ideas on how to proceed.. ?

Thank you in advance

Which dash light on? You mean the red battery light stays on?
Any DTC so I can submit the pinpoint test?

jpearson Apr 22, 2025 02:42 PM

Hello,

Thank you for the reply and my apologies on the lack of clarity.

No DTC codes, just "RED" battery lights comes on after 2 mins and stays on.

Alternator is charging/operating voltage fine.

No open circuit between alternator and PCM.

If there are additional checks, please elaborate...

Thank you in advance.

Take care,

J
