Ilikeoldfords: I still have my original PCM. I kust swapped the harness from the manual truck so he could have the auto plugs needed for transmission. I think the manual harness is wired a bit different than the auto trans harness since I lost cruise control. Everything else works with no issues. I have full engine power, etc... I think a manual PCM is required, unless someone knows how it needs to be wired.

I currently have a 99 QCLB that I recently swapped an NV5600 from a 2001 QCSB. I swapped everything excluding PCM or ECM. I even swapped PCM harnesses. My issue is that I lost cruise control in the process. If someone has a manual PCM for a 99, I can let go of mine for a whatever the manual PCM costs. Maybe we can help each other. My truck drives perfect otherwise.
