I will create spreadsheets that tell you which pins are different so you can wire a T100 4x4 Auto ecu to your 3.4 4Runner 4x4 Auto loom. This will fix the speed sensor issue and the sometimes inaccurate transmission shifting. You will also gain 1 - 2mpg. This only works for early 2nd gen 4Runners with the mechanical speedo (90, 91, very early 92's)

I will start with the '98 4Runner 4x4 Auto ecu because thats what I have.

There will be no time frame in completing them and I'll not be responsible for you destroying anything on your vehicle. These will be a guide only, educational purposes, and there may be mistakes. You follow them at your own risk. Sometimes color of wires on the vehicle differ from that of the FSM. I have no way of checking out those anomalies.

 

I have one for a 95 T100...not sure if that would help or not....let me know if you would like me to send it to you.

 

Sure, send it. I'll take a look. I can also compile a list of wires changed for same ecu type but different years.

I'm surprised no one has jumped at this offer.

 

I have the '97 stuff. PM me yur e-mail and I'll send them over. Zipped they are just under 6 mb.

 

Thank you for doing this! I'll be waiting for the '97 4runner auto to '95 T-100 myself

Thanks again.

Andrew.

 

I'v been looking at the EWD's... My 97 4Runner engine did not have a EGR, I've looked at a 95,96 and 97 T100 and the ECU has a sensor for the EGR. Is this going to be a problem?

Thanks!

 

I also am looking for this ewd, you still have it?
