Help with stock EFI

I’ll be watching this thread. I did a 5.9 Magnum swap into my Jeep in 2003. The motor was out of a 99 2500 4wd auto truck and went into my 88 Wrangler. At the time I was running a NV4500 5 psd. Make sure you grab the harnesses, fuse box, instrument cluster and fuel pump out of the donor. You won’t know what you need until you need it. For my swap I spent a month to marry the 88 Jeep harness with the 99 harness. Using a FSM for that year truck and the 88 FSM. Made it all work.
Started out using a manual tranny computer but eventually found someone to reprogram an auto tranny computer for more HP and he was able to bypass the auto tranny features.
You’ll definitely want to keep the OBD plug for diagnostics.
Anyway I’m here for free advice if needed.
