I've only seen pictures of the engine and harness. The smart phone pictures are poor quality. It appears the harness is from a LS1b PCM (green / blue). The only clear picture I have shows the ECM / PCM connectors cut from the harness. The original PCM is not available, who knows where it is. The engine has seen several owners recently. My job, is to build a custom harness and flash a PCM. I find it very interesting that Current Performance builds a harness for the same vehicle application that requires two computers, so monkey see / monkey do?
Actually this is whole project is a nightmare in the making!

I'm challenged by the option of the DBC option, seems like a good plan would be to use a native PCM / Flash for the L33.

Would the L33 PCM correctly operate (plug-n-play) the 1996 4L60E?
