Still need a 5.2,M/T computer, though. It will run and drive with the A/T computer, but as others have mentioned, you'll have a permanent MIL with P07XX and other trans codes up the wazoo.

Very true, just add two injector connectors with appropriate wiring and lengthen coil and alternator pigtails a few inches.

How would I add the 2 injector connectors to the current computer? Or use the computer from the donor truck and have all the tranny codes stay on?

M/T= Manual Trans
MIL= Malfunction Indicator Lamp. Another term for check engine light.
The six cylinder wiring harness simply won't have the wires for the two additional injectors, however, the cavities in the PCM connectors will still be there. Not sure if the six cylinder computer will have outputs for them though.... getting a PCM from a V-8, manual trans truck would be best. (same year as your truck please.)
Adding the wiring for the injectors is just time consuming. You could scavenge those from the engine donor truck, along with the wires for the coil, and alternator. (as opposed to lengthening them, up to you on the last two) Simply a matter of getting the wires out of the old harness, and putting the into the new harness. (make sure you plug them into the correct cavities on the PCM connector.....)
