PN 89661-35350
1990 pickup 4wd m/t 3.0
It has 10 pin ,18 pin and 24 pin connectors .
Truck will not run with TPS plugged in, I think I need to check the resistance of the wiring to the ECM.
The 1993 FSM is different, done many other searches as well.

This may be from an '88 or '89 dunno, but it looks pretty close if anyone else needs it.

Get a copy of the EWD for that year.

I watch Ebay and if I can get a EWD for a good price I buy it.

If indeed that ECU/Ecm is out of a 1990 .

Trying to use any other year is going to get real frustrating .

Not only can the pins be different the wire colors as well

If I had a copy of that year I would be happy to give the information to you.

Since Toyota Sold the rights to the service manuals to Helm Inc prices have tripled and Helm has forced most of the online copies off the internet.

To make it worse Helm Inc if they don`t see a demand for a product the obsolete it.

Here is the pin out I use http://media.photobucket.com/user/ad...g.html?filters[term]=1989 toyota pickup ecu pinout&filters[primary]=images Toyota does like to change some wire colors from year to year when everything is the same. It can be frustrating.

Not sure what happened, it is someone else's Photobucket I have a link to https://www.yotatech.com/forums/f199...l#post51897320 When I click on it, the ECU pin out is showing for an 89 which is close to yours. Let me know if it shows up wrong if you don't mind.

When I go to the link in the post above this one, there is a link to the Nissan. Going to the link from my thread it takes me to the Pinout.

Trying to use the wrong schematics is like trying to use a Map of Houston Texas to get around Boston Massachusetts !!!

At worst it fries the ECM If your lucky it just does not work.

OK I can see Terrys pic but it's not the same. Mine is 10/18/24 pin connector for 3vze 1990.
Yeah the ecm may have been fried when I bought truck but it will run without TPS connected. Hate to install another ECM and cook it too.
