RET to RE
I’m working on a 4Runner probably and 87 that had a 22RET but the engine in it is an RE. It has an automatic transmission. Is there anything as far as wiring that needs changed? Someone put a Weber carburetor but left all of the wiring for fuel injection. Is there any difference between a RE and RET computer? I have another computer from another automatic or I also have a manual transmission and parts. Petals with clutch sensor, master and slave cylinder, transmission mounts, drivelines, and everything else. I know the rear and front gears are different on an automatic. Is there anything else I need to know for transmission swap if I go that route (automatic to manual)?

You are all over the map man.
How about we skip all the random ish questions and you.tell us what it is you want exactly?
You have a 1987 4runner, it has a 22r with a Weber, it's hooked up to an a340h, the efi wiring is intact.
It runs? Where is the problem?

I have a Toyota 4Runner that had a 22RET with an automatic transmission. At some point someone replaced the motor with an RE. They took the fuel injection off and put a Weber carburetor. The vehicle doesn’t run. I pulled the motor and am going to put another rebuilt 22RE motor. I would like to restore the fuel injection so it runs correctly. My only question is about the wiring. Is there anything different I have to do as far as wiring? The computer is from a Turbo motor. Not to be confusing but I have several other Toyota’s for parts. I have another computer from an automatic without a turbo. Should I swap computers and wiring harnesses? Another option I was exploring was swapping to a manual transmission. I have all the parts to go that route also. I guess I’m just looking for a second opinion on what to do. I have rebuilt or fixed 6 Toyota’s with 22R or RE since February. This is the first automatic I’ve had to deal with. Anyhow I’ll look at the numbers on the computer and see if it’s the same with or without turbo.

If ypur asking multiple questions sometimes its better to break them up.
Something like this.
And then it helps us pick certain answers that we may know.
You have not stated a problem that i can find. It sounds like you have a running rig and a lot of parts. As for your trany swap questions. A search in the fab shop section will probably get you started. I am sure the wiring is at least a bit different between the RE and turbo. Having a donor harness would be best.

If it has a Weber then there is no computer. Except for maybe some smog controlled stuff but normally you would just de-smog with a weber. All you need is power to fuel pump if it's electric, if its a mechanical fuel pump then no power needed. Power to coil/igniter. Nothing controlled by an ECU though.

Yes change the ECU, the turbo version uses different trim tables for fuel spark ect.
Transmission, the turbo trans has a different gear ratio, iirc slightly different shift points. Should be fine with either ECT computer.
ECU not directly swappable, you will need to go over the wiring diagrams for both ECU model years and variations. There are a few pins/wires in different places.
Pretty much treat it like any other engine swap. Meaning you need both wiring diagrams, multimeter, and the wear with all to go over each wire from source to ECU.
I think getting it running on the Auto ECU would be faster and easier than converting to manual shift. Converting to manual shift is similar to above, lots of double checking, with the added complexity of pedal brackets, hydro lines, master/slave..

I swapped a 88 22re into a 86 22ret with auto trans and 4x4 ,The injectors were different ,so the 86 injectors were used with the ret ecm.The o2 sensors were different,
so I used the 86 and drilled and tapped the exhaust manifold. I also swapped any parts that would not plug into the 86 harness.
The main problem was lack of power ,it might have been the axle gearing or other things mentioned above, but the truck ran good without problems.
