Right off in addition to the things you mentioned. The engine harness is different and manual/automatic specific. The body harness is the same. If the 3.0 is flex fuel you may need to change the frame harness to get rid of the "fuel valve" under the drivers seat mounted on the frame. You will need new compressor hoses, on the 4.0 they run behind the engine and on 3.0's they are in front. When you change the computer you will most likely run into a pats problem. The computer won't recognize the original pats keys from your truck so you should get all the locks from the donor truck if possble. Also the radiator & heater hoses, the crossover pipe, cruise cable, intake tube, and MAF sensor.
