3.4 swap with auto trans wiring help needed!
First off I am new to the site, but not new to the offroad scene. However I am new to the 3.4 swap I am trying to complete. I have a '93 4runner with the 3.0 4x4 and auto tranny. Donor motor was from a 97 4runner 3.4 auto tranny 4x2. I was able to purchase a 97 t100 ecu, as I was told the t100 ecu would control the auto tranny from 93 4runner. My question is about the wiring, and which wires in particular need to be repinned. I have read through several threads and write-ups, clicked on many links, but none seem to show the diagrams for the repins. I have heard that it is only a couple of wires that need to be moved. Can someone point me in the right direction please? Thanks in advance.

^ Get the EWDs. You need a relay to activate the solenoid for 4L. Everything else works right out of the box. It's really not hard- at all, just sounds intimidating. Good luck.

Heya, I've got a printout somewhere, I'll snap a pic and put it on.
(I also bought an OBDII extension off of amazon to wire in, and put the connector in the glove box. I do know that it is a 15 ohm resistor; I thought it was a 15k Ohm and I couldn't get it to work, again and again; but when I checked my t's and i's I found the discrepancy.)
