So here a few weeks later I made the swap. I might say it was actually really easy. Much easier than I expected. I appreciate the tips they came in handy. I had to get an crank sensor and flywheel for the manual. Otherwise it was pretty much wire up about 4 wires through the PDC and fire it up. I have driven it probably 30 miles so far and I love the way it runs. I used the 99 harness and controller I was not able to get it reprogrammed yet but not exactly sure if I'm going to need to. Even the fuel tank bolted in with the fuel line out of the 99 with minor modifications. I have a couple wiring issues to clean up but I was impressed how smooth everything went and especially the way the truck runs now. I thought the LA I had was a pretty hard runner after I built it but this magnum is pretty sweet. Thanks guys for the tips and if anyone has any questions while this swap is still fresh in my mind feel free to ask.
