Hello, I need to get pinout diagrams for PCM and 42 Pin Connector please? I actually have wiring diagrams I can look at for the PCM, but I don't have a reference for the 42 Pin connector. Thank you, Alex.

P.S. A pinout of the CCRM would be appreciated too.

So you have the pinout for the 42 pin connector that the fuel injection wiring harness connects to. It is the one on the passenger side fire wall. Thanks, Alex..

Just to jump in on this, it doesn't look like we have a 42 pin connector but I suspect you are talking about an inline connector?

If so, we have C104 which feeds the injector splice but that is a 39 pin connector.

So, I am attaching the info below of the layout diagram and then the pinout of this inline.

Please let us know if you need something different and we can go from there. Thanks
