03 swap to 06 ECM

Ok so to do this swap all is needed is ecm and engine wiring harness or full harness of truck? Also what about the tipm?

Depends on if you want factory gauges and a/c. If you do then you've gotta swap the dash and dash harness out. Also requires the steering column to my knowledge.

EVERYTHING in these trucks is hooked up. Even the factory radio (although that would work regardless)
 
so to get the basic to work you need to swap engine harness and ecm, Im going to run it in a ford so I have a whole other issue for gauges
 
You will also need an 06 rocker box, valve cover, and VC wiring harness uncless you want to cut and splice the injector plugs from the 03-05 harness.
 
having the ford and cummins harness made, it will have the 03-05 injector plugs on it, the rocker box and VC have already been swapped on the motor
