4RunnerGuys 4Runner 1uz swap

Finally desided to go head with the project.

is there anyone that sells the motor mounts for this project?
im also keeping the manual 5speed, and all be getting into detail on wiring harness for the people that feel brave enought to do it there own.
All so cause no one has a detailed wiring diagram.

will be posting a vid of what happend to my 3.slow tomorrow

4runnerguy, whenever I needed help with wiring, I consulted the following FSM:

1990 Toyota 4-Runner Factory Service Manual:

http://rapidshare.com/files/34006966...0.1995.SIL.rar
OR
http://www.ncttora.com/fsm/1990-1995....1990.1995.zip


It has both wiring and mechanical section. The wiring folder has all PDFs which are color coded so you can exactly which wire is what. Other than those, I also consult my chilton manual which wiring section too.

Another Link: http://www.snjschmidt.com/wiring/

For ECU Pin out for 1991 4Runner 3VZE, download the above FSM and look into the section:
Engine->MFI System--ECM

Here is the 1993 Pickup ECM Pinout hosted online (this might be bit different than yours): http://personal.utulsa.edu/~nathan-b...ne/44engin.pdf

Best thing would be if you have wiring section of 1991 3VZE, but I think 1990 would be your best bet for now. Hope this helps and good luck!

Im curious what happened to your 3.0 .. you gotta post that video

The harness your using is it from an ls 400 or sc 400 .. is the plug attached to the same harness that goes to the battery or are you pulling it towards the battery...the plug looks like its the oxygen sensor plug.
