I really don't think that anyone has done it yet. Honestly the only thing you would have left after the swap would be the 04 body and interior. You'd have to change out everything, swap all the wiring over. Like I was saying in the other thread the 04s use a SJB instead of a GEM. You would have to swap almost every single wiring thing over, change the gauges back to 03 and tons of other stuff. It would be easier just buying a 03-

I need to look into this further. I know the gages changed and went to electronic Odometer, but what are the major changes that cause the issues? And SJB and PCM have nothing to do with one another. All fuel injected for vehicles have a PCM or some sort. There are several different software versions.
An SJB is a smart junction box more similar to a GEM - general electronics module.
I have thought hard about selling my 1999 and making my 2005 the project truck, now this throws another twist.
Here are my thoughts on Ranger V8 swaps derived from reading and from my experiences while swapping my 2003. No guarantees but I think this is accurate.
1997-back has good aftermarket support with many off-the-shelf swap components that will match up just about any small block Ford V8.
1998~2000 Rangers are a very close cousin to the 99~2001 Explorer 5.0L so, IMO, these are the best choice for an easy later model Ranger V8 swap. VSS and ABS, the fuel system and most of the electrical system are a very good match. 99~00 V6's have the same Type B PATS system. All 98 Rangers and 99~00 4-cylinders would need a simple PATS transplant or a countermeasure to defeat it.
2001~2003 adds some funnies with the PATS, 4WABS and the VSS. Still, the vast majority of the wiring is compatible with the 99~01 Explorer engine/trans/PCM/fuel system.
2004~2006 Rangers had a complete harness tearup compared to earlier years - almost nothing was left untouched with a lot of routing, connector and color code changes. Also, from my perspective, the electronic cluster might be an issue. Unlike earlier years, the 2004~2006 has an onboard microprocessor that is tied into many vehicle functions and talks to the PCM over the Module Communication Network. It is not clear how many problems this might cause and that probably won't be known until someone actually tries it. I suspect that it would be doable but might be a pretty serious can of worms.
2007~2008 have the newer 175-pin PowerPC processor, all new harnesses with new color codes and connectors and a revised Smart Junction Box. They also got an all new cluster/microprocessor that took over the PATS function among other things. The speedometer no longer gets its info from a dedicated wire but appears to communicate it over the CAN bus. These trucks have everything that could make a 04~06 complicated only MUCH more so.
^ depending on how much time you have and if you have all the parts. i know some have done the swap in a weekend. But yeah the SC is deffinetly a faster less painful job. At somepoint if i still have my truck, later on I'd like to SC the 5.0
I'm in the process of building a monster of sorts. All these lovely tools, engine/suspension parts, bending/welding things..
ANYTHING can be done but the most detrimental factor will be the person doing it. Its not a ' wallet ' issue or a time issue, its weather or not someone feels up to the task of dealing with problems that WILL happen.
For simplicity, buy the EE kit and be done with it. Its a 6-8hr project for the average person and requires nothing more then regular handtools and reading instructions. Bang for the buck, it fairs poorly against a v8 but for the ' I can do this ' factor, its MUCH easier!
