So I decided to do the swap instead of the 3.0 rebuild. I have a complete running engine out of a 99' 2wd auto 4runner with ecu and all wiring (engine/dash/fuse boxes/gauges). I need the ecu pinout for both a 99 auto 4runner, and a 00 manual 4runner that i scored an ecu out of and am trying to use in my swap. Any extra tips or hints for my swap would be appreciated. Thanks in advance guys.

I must 2nd 69 on that. It is the only way that you will be able to do the wiring on your own.
It's only $15 for 2 full days of service. Register and download everything in the EWD section for the year of your donor (plus the year above and below) and do the same for the the truck/4Runner that you are putting it in. It does take a little while to get all of the information but it well work it in the end. Remember to get the years above and below both your donor and recipient for cross referencing wiring that may not match exactly to you truck/4Runner. You will be money/time ahead by doing this.
