So I thought, looks like my cross-reference is not reliable, bummer.

This is what I would do. Also, I think the FSM has the resistance values published for the sensors/solenoids as part of the testing documentation.

-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.

Looks good to me, only thing I would mention is the drive shafts. Some have made the auto ones work, but you have the manual ones, you might as well use those, that's wgat I plan on doing.

Ok. So here's a question....
Your runner is a 97, right? The donor is a 96, right?
Why not just pull the ECU and The harness and put them in your truck?
Speaking from experience, it's not hard to do at all. Pull the intake off, and disconnect everything. Takes about 45 minutes to do.
As long as it's a 3.4, everything should plug together, except for MAYBE the injectors. But just swap them out and you should be fine.
Just my .01.

ALL info needed for a 97 4Runner 5 speed swap. Wire details included and no ECU swap.
5spd swap, HERE GOES NUTHIN!
Keep the 5 speed t-case and use the 5 speed shafts and cross member. Easiest way.
I am still running an F1 Racing clutch but had to upgrade to stage 3 due to the super charger and the rock climbing abuse. Now it bites hard as hell!
Marlin Crawler Taco Box 4.7 is in the near future.

That's an idea but it seems like a lot more work than necessary. I'd rather just swap in the ECU.

Interesting. I read your thread. I see you stuck with the auto ECU. I am pretty attainment on using the M/T ECU.

Im planning on swapping the harnesses. Especially because there us a good chance you could fry the ecu.
Since the ecu is the rarest and one of.the more expensive parts, i wouldnt risk it. But its up to you.

Hmm... Does the harness run behind the dash? If so, that seems like A LOT of work.

No. No it does not.
take the glove box out. You can see the ECU up in there.
the firewall on the passenger side, there's a little rubber boot.
the ECU harness exits the firewall, runs to the engine and trans. It has connnectors for the BODY harness, but the majority of it goes out the firewall.
hence why I said to change out the harness as well.
Disconnect everything from the ENGINE and TRANSMISSION, that's really it, and then swap in the manual harness.

Oh good.
Yeah I already have the ECU out. Maybe I will swap the harnesses that seems like the best bet.
Edit: The more I think about it, wouldn't it just be easier to find a 1997 manual trans V6 ecu?

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

This is true. Without a manual ECU available, you are going to have to fool your ECU into thinking the transmission is still there. You can do this using a method mentioned below by Singtoe.

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.
A great quote on TTORA from mosk

Tacoma ECUs are different I believe. I know they were in 1998, the year of my 4runner, so you can't just pull a Tacoma one without running the same risk that the OP would run by popping in the ECU he already has from the 1996 donor vehicle.

I think this would be the best way to do it without an ECU. A fella over on TTORA I think started this project before we found a way to swap in manual ECUs without frying them. Unfortunatley, that information is not freely available for 4runners. The guys on TTORA compiled the data about ECUs for the Tacomas. I just got lucky that the guy doing the work had a 1998 4runner and the data for it.

You run the same risk that I mentioned before. There is no way of knowing that the manual and auto ECUs have the same pinouts. You could get the info by buying a one day subscription to the toyota information system. If you go to that thread on TTORA that I mentioned in an earlier post, you can get an idea about the differences between the manual and auto ECUs. Truthfully I have never compared any ones other than the ones for a 1998 4runner, but I know that in 1998 the ECUs were different.

Leaving the ECU issue aside, the rest of the wiring is pretty easy and should be documented on my thread on TTORA. The wiring on the transmission harness may be different, but you could check out Bawlz's thread. His is a 1997.

Here is another thread that may be of use. This fella was doing his swap the same time I was, so we exchanged thoughts on a number of things. A340F- to -W59 - TTORA Forum

I don't think i'll need to do any other wiring with the ECU aside from plugging it in.

Hmm interesting, I will check it out.
Basically, as far as i'm concerned, here is a list of the wiring I have to do, correct me if i'm wrong.
-There are 2 switches on the brake pedal assy, I am assuming I already have that wiring in my auto.
-There is a switch on my clutch pedal assy which needs to be wired up
-There are 2 pigtails on my transmission 1 is for the reverse lights and what's the other for?
-There is the clutch cancel switch

I will be interested to hear how the ECU works out. Keep us posted on that one. I have a 1998 manual ECU that I have yet to swap in.... CEL has not bothered me much after three years.
No work needed for brake pedal. There should be two switches on the clutch pedal. One at the top and one at the bottom. The one at the top will disengage the cruise control and the one at the bottom is the neutral safety switch. I think this is it, but this is all from memory of work done three years ago now...
Do you mean 2 pigtails coming off the auto transmission? I know I had unused wires that ran to the auto tranny after the swap. I am pretty sure I only hooked up the reverse lights to the transmission.
Let me know how you wire the clutch cancel switch. I finally picked one up, but I have not wired it in yet.
