3.4 swap need help
#24
Your best bet is to figure out what most of the sensors are compatible with, the 2000-2003 Tundra would be a good start, then find a used ECU at a junk yard, then rebuild the harness and do the swap to match whatever ECU you find.
If you need to pass any sort of emissions after the swap, you're going to need to be extra careful to get the right parts.

I have no idea, but as I mentioned in a previous post, it looks like you have a mess on your hands.
The engine itself (minus any of the sensors) will be fine, I'm sure they were pretty much all the same, but you're going to have issues with the electronics.
Eventually you will need to pick an ECU, it could be at random or after a thorough inventory of all your other electronics, and then "make it work". By that I mean, you may need to buy all new sensors, VSVs, etc to work with the ECU you chose.
The best you can hope for is write down the part number for everything that plugs into the engine harness, look up those part numbers online, write down everywhere they were/are used then pick an ECU from an application that has the most matches to the sensors you have.
I only mentioned the Tundra because you posted a screen shot of a VSV that was used with the 00-03 Tundras, if you're lucky most of the other sensors will also work with those Tundras.
Some times a "good deal" isn't always a good idea, that's generally why the standard advice is to buy a whole donor vehicle, or to make sure and get everything from the same vehicle.
