Lb7 manual harness pinout

[Justlikethat]

Hey guys I'm needing the engine harness pinouts/diagram for a 2003 lb7 with a manual transmission. The harness that goes to the fuse box the big black plug I forgot the plug name. And also looking for the same pinout/diagram for a 2001 lb7 with automatic transmission

I'm doing a manual transmission swap on the 01 lb7 and I got a manual transmission out of a 03 lb7 and also the whole engine/trans harness but the pinouts on the manual transmission harness are different that plugs into the fuse box.

If anyone has those pinouts and be willing to help me out that'd be much appreciated. Thanks

Your biggest issue is going from an 01 to an 03. 01-02 has a different fuse box layout compared to 03-07.

Yep exactly so I'm just trying to either make the 03 harness work or just keep the 01 harness and just have the safety neutral switch tucked underneath somewhere
