Hmm I might try plugging in the donor ECU anyway, worse comes to worse I will just fry that ECU and have to buy a correct one anyway.
I'll check out your thread for the wiring.

I have a question for you guys: I've seen threads like this and in my daydreams I've thought that if my auto trans ever dies, it might be cool to switch to a manual. I have a 2001 with vsc/trac and the multi mode transfer case. If i did the swap, would i be able to keep the multi mode and the vsc/trac?

In theory you can, it just gets more complicated wiring wise.

Even if you manage to get the 5 speed bolted up and get the transfer case working, your year limits to only automatic transmission compatible ECUs. You'll throw a CEL for the missing automatic transmission components. There will be a lot of now defunct wires left over from the auto transmission harness.
Manual swap in 01-02 would not be a fun thing to do IMO... 99-00 have manual transmissions available, making an ECU swap of the same year a solution to auto ECU CEL's. I don't think theres a way to make the auto ECU not throw codes. That could be annoying to look at daily, moreso when inspection or smog come around

Agreed. Not worth it IMO.

While you are correct with the defunct wires that will need to be stores somewhere out if the way, there is a way to keep that CEL from being on.
It takes some studying, some creative thinking, and time, but if you can figure out which wires need to be connected to make the ECU think the transmission is in NEUTRAL, you'll be fine.
You won't get any CELs, and you'd be able to pass inspection, if you needed to.

Yeah I got it about 3 weeks ago now. As you know, these are hard to come by in our area.

I disagree.
Wiring the neutral safety switch isn't going to fix it. A 3.4 auto ECU will definitely throw codes, there are missing solenoids and sensors. Those will be missing whether or not you're in neutral.
Here are some codes I found online of typical 5 speed swaps on the 3.4 using the automatic ECU:
P0710- Transmission Fluid Temperature Sensor Circuit Malfunction
P0753- Shift Solenoid B Circuit Electrical
P0758- Shift Solenoid B Circuit Electrical
P0773- Shift Solenoid E Circuit Electrical
Is there a way to manipulate the ECU into thinking the missing parts are there and in functioning order? If even a malfunction can throw a code, the readings must be very specific.. I don't see how it could be done without ridiculous amounts of extra effort, or a simulator of some sort. I'd start looking at 2002 Tacoma 3.4 5speed ECUs and try to get one of those to work, there's pinouts online and in the FSM, it could be compared and repinned if need be. I am unaware of differences maybe involved with throttle by wire or other Tacoma/4Runner differences, but that's a good place to start looking.

I think Toyota optimized the factory fuel and timing maps differently for the auto vs. the manual transmission vehicles, to meet CAFE requirements (fleet economy) and for emissions. That (and CA emissions) are the main reasons I want to do the ECU swap instead of keeping the auto ECU and tricking the computer. I've had enough of tricking computers . If I'm going to spend the money to convert this truck to a manual, I want to drive it with the right fuel maps, the right timing maps, and no CELs. Been there, done that.

WADR,
I didn't say the neutral safety switch.
Make the ECU think the transmission is in neutral.
This is from a '91, but same principle:

Re-railing this thread for a moment.
Here's a list of what I have pulled for the swap, please let me know if I am forgetting something.
-Manual trans
-T-Case
-Shifters
-Shifter trim
-ECU
-Driveshafts
-Clutch pedal assy and all connectors
-Brake pedal assy and all connectors
-Clutch cancel switch
-Clutch (will be replaced)
-Flywheel (will be replaced)
-Master cylinder
-Slave cylinder
-Clutch lines
-Crossmember
I think that's it, right?
I'm still super confused on wiring. That's basically all that's holding me up right now.

I think the easiest way to fix this is to Take an ohm reading of each solenoid and buy the equilivant ohm resister and wire it in.
The ECM will see the load on the circuit and think all is fine.
Do the same for the Temp sender. Find a ohm value for the correct temp and wire the corresponding resister in place.

According to the Toyota Parts Cross-Reference, the part number 89661-3D140 (which is the number on my ECU) fits 1996-2002 4Runners. I think i'm gonna try it in my 97'

So not true.. 2001 and 2002 4runners are drive by wire and that by itself would need a totally different ecu.
